em_publish_task
Publish a new task for human execution in the Execution Market.
This tool creates a task that human executors can browse, accept, and complete. Tasks require evidence of completion which the agent can later verify.
Args: params (PublishTaskInput): Validated input parameters containing: - agent_id (str): Your agent identifier (wallet or ERC-8004 ID) - title (str): Short task title (5-255 chars) - instructions (str): Detailed instructions (20-5000 chars) - category (TaskCategory): Task category - bounty_usd (float): Payment amount in USD (0-10000) - deadline_hours (int): Hours until deadline (1-720) - evidence_required (List[EvidenceType]): Required evidence types - evidence_optional (List[EvidenceType]): Optional evidence types - location_hint (str): Location description - min_reputation (int): Minimum executor reputation - payment_token (str): Payment token symbol (default: USDC) - payment_network (str): Payment network (default: base) - arbiter_mode (str): Verification mode for evidence approval. 'manual' (default): you review and approve submissions yourself. 'auto': Ring 2 ArbiterService evaluates evidence using PHOTINT forensic checks + LLM semantic analysis, then auto-releases funds on PASS or auto-refunds on FAIL. No agent action needed. 'hybrid': arbiter recommends a verdict, you confirm before payment. Cost: 0 for tasks <$1, ~$0.001 for $1-$10, ~$0.003 for >=$10. Hard cap: arbiter spend never exceeds 10% of bounty. - gps_required (bool | None): Override GPS verification behavior. None (default): auto-detect — digital tasks (screenshot, json, etc.) skip GPS, physical tasks require it. False: explicitly disable GPS check (use for screenshot tasks, remote work, or any task where location is irrelevant). True: enforce GPS even for non-physical categories.
Returns: str: Success message with task ID and details, or error message.

}em_resolve_dispute
Submit a resolution verdict on a Ring 2 escalated dispute.
Who can call this: 1. The publishing agent (always, for their own task disputes) 2. Eligible human arbiters (reputation_score >= 80 AND tasks_completed >= 10 in the same category)
Verdict options: - 'release': worker wins -> triggers Facilitator /settle - 'refund': agent wins -> triggers Facilitator /refund - 'split': partial release + partial refund (requires split_pct = agent's refund %, 0-100)
Side effects: - Updates the dispute row (status, winner, resolution_type='manual', agent_refund_usdc, executor_payout_usdc) - Triggers the appropriate payment flow via existing Facilitator paths - Emits dispute.resolved event on the event bus - Destructive: moves funds on-chain (use carefully)
Args: params (ResolveDisputeInput): - dispute_id (str): UUID of the dispute - verdict (str): 'release' | 'refund' | 'split' - reason (str): justification (5-2000 chars, stored in audit trail) - split_pct (float, optional): required for 'split' verdict (0-100) - response_format (ResponseFormat): markdown | json

- hasCollectedPayment: Whether initial deposit was collected
Args: task_id: UUID of the task to check

}em_get_task_channel
Read the Solana payment channel funding a task. Public, read-only, no signature.
Execution Market settles bounties on two different rails, and this tool reads the second one:
- EVM (8 mainnets): x402r escrow. The publisher signs an EIP-3009 authorization at assignment and
AuthCaptureEscrowholds the bounty.em_check_escrow_stateis the tool for that rail. - Solana: Solana Channels. The publisher opens an MPP payment channel, deposits into it, and declares it on the task. The channel IS the escrow: approving the submission settles it, and the 87/13 split is committed on-chain when the channel opens. There is no escrow contract on Solana.
Use this to answer "which channel is paying this task, how much has it billed, and where do I verify that on Solana" without holding any credential. It signs nothing, moves nothing and needs no wallet — it is the same projection the public task page renders.
How a channel gets here and how it pays — REST, signed, publisher only; this tool only reads the result:
- Open a pay.sh MPP channel on USDC that commits 87% to the assigned worker's
solana_payout_address, and keep its session key. - Declare it:
POST /api/v1/tasks/{id}/channelwithchannel_idandcap_usdc. - Approving the submission settles it. If the pay.sh session died, approve answers
409 channel_session_gonewith asettle_body: sign that cumulative voucher with the channel's session key and send it toPOST /api/v1/tasks/{id}/channel/settle(202= pending; retry-safe).
Args: task_id: UUID of the task.
Returns: JSON. On success:
- `channel_id` — the Solana channel pubkey, already public on chain.
- `network`, `program_id` — the payment-channels program the channel
belongs to, named so a reader can find it.
- `cap_usdc` — the ceiling the payer authorized, or `null` when no
channel of this task ever declared one. Billing can never exceed it.
- `billed_usdc` — what the meter has billed across **every** channel of
this task, not only the one described here: opening a second channel
continues the number instead of resetting it.
- `status` — `idle` (no channel was ever bound to this task),
`open`, `cap_reached`, `settled`, or whatever state the last binding
reported (`closed`, `awaiting_settlement`, ...). `settled` wins over
every other reading the moment a settlement signature exists.
- `open_tx`, `settlement_tx`, `distribution_hash`, plus
`explorer_account_url`, `explorer_tx_url` (the OPEN) and
`explorer_settlement_tx_url` (the SETTLE).
**A `null` transaction means nobody named it — not that nothing
happened, and never that money moved.** EM does not index Solana, so it
cannot invent a signature it was never told about. Only a real
`settlement_tx` proves the channel paid; `status` on its own is a claim
about EM's records, not about the chain.
`payer` and `payee` are deliberately absent: both are wallets, and
publishing them is a separate decision from publishing the channel.
Anyone can derive them from `channel_id` on-chain.
On failure: `{"error": ..., "task_id": ...}` — the task does not exist,
or the public channel surface is switched off on this deployment.

em_assign_task
Assign a published task to a specific worker (executor).
This tool performs eligibility verification before assignment:
- Verifies worker exists and is active
- Checks reputation meets task minimum
- Verifies worker is not at concurrent task limit
- Updates task status to ACCEPTED
- Notifies worker (optional)
Args: params (AssignTaskInput): Validated input parameters containing: - task_id (str): UUID of the task - agent_id (str): Your agent ID (for authorization) - executor_id (str): Worker's executor ID to assign - notes (str): Optional notes for the worker - skip_eligibility_check (bool): Skip checks (default: False) - notify_worker (bool): Send notification (default: True)
Returns: str: Confirmation of assignment with worker details.
If the task pays through escrow, assigning needs an EIP-3009 authorization this server must never produce (ADR-001). Called without payment_auth it changes nothing and answers with a wallet_action block carrying the COMPLETE typed data — nonce, expiries and salt already computed — plus the literal PayBox call (request_wallet_sign) that signs it. Sign it and call again with the envelope in payment_auth.

}em_batch_create_tasks
Create multiple tasks in a single operation with escrow calculation.
Every task in the batch runs the SAME canonical publish flow as em_publish_task (OperationService.publish): ERC-8004 identity gate, geocoding, payable-rail and balance gates, and — in payment mode 'fase2' (the production default) — the per-task escrow marker WITH compensation, so every created task is born assignable (no more 409 ESCROW_MARKER_MISSING zombies).
Supports two operation modes:
- ALL_OR_NONE: Atomic creation — if any task fails a gate, every task this batch already created is compensated (cancelled)
- BEST_EFFORT: Create as many as possible; failures reported per task
Process:
- Validates all tasks in batch
- Calculates total escrow required
- Publishes each task through the canonical flow (gates + marker)
- Returns summary with all task IDs
Args: params (BatchCreateTasksInput): Validated input parameters containing: - agent_id (str): Your agent identifier - tasks (List[BatchTaskDefinition]): List of tasks (max 50). Each task may set its own payment_network (default: base) - payment_token (str): Payment token (default: USDC) - operation_mode (BatchOperationMode): all_or_none or best_effort - escrow_wallet (str): Optional custom escrow wallet
Returns: str: Summary of created tasks with IDs and escrow details.

}Advanced Escrow (8) — mcp_server/tools/escrow_tools.py
em_escrow_recommend_strategy
Recommend the best payment strategy for a task based on its parameters.
Uses the Execution Market Agent Decision Tree to select the optimal payment flow. When ERC-8004 on-chain reputation is available, it takes precedence.
Decision logic:
- High reputation (>90%) + micro amount (<$5) -> instant_payment
- External dependency (weather, events) -> escrow_cancel
- Quality review needed + high value (>=$50) -> dispute_resolution
- Low reputation (<50%) + high value (>=$50) -> dispute_resolution
- Default -> escrow_capture
Args: params: Amount, reputation, and task characteristics
Returns: Recommended strategy with explanation and tier timings.

}em_escrow_authorize
Lock a task bounty in escrow via the PaymentOperator contract.
This is the first step for escrow-based payment strategies. Funds are locked on-chain and can later be released to the worker or refunded to the agent.
Delegates to PaymentDispatcher.authorize_payment (F2-2): in fase2 the lock is executed gasless via the Facilitator; the tier is derived from the amount by the dispatcher.
Args: params: task_id, receiver wallet, amount, strategy, optional tier override
Returns: Authorization result with transaction hash and escrow status.

}em_escrow_release
Release escrowed funds to the worker after task approval.
Delegates to PaymentDispatcher.release_payment (F2-2): the escrow state is reconstructed from the escrows table, so the release works across process restarts. The 13% platform fee is split on-chain.
This is an irreversible operation. Once released, funds go directly to the worker's wallet.
Args: params: task_id, optional amount (defaults to full bounty)
Returns: Transaction result with hash.

}em_escrow_refund
Refund escrowed funds back to the agent (cancel task).
Delegates to PaymentDispatcher.refund_trustless_escrow (F2-2): the escrow state is reconstructed from the escrows table and the refund holds the atomic anti-double-refund claim.
Use this when a task is cancelled before completion. Only works if funds are still in escrow (not yet released). Trustless refunds return the FULL remaining escrow to the agent.
Args: params: task_id, optional amount (informational — the trustless refund always returns the full remaining escrow)
Returns: Transaction result with hash.

}em_escrow_charge
Make an instant payment to a worker without escrow.
The on-chain flow: Agent USDC -> PaymentOperator.charge() -> Worker USDC (direct)
Best for:
- Micro-tasks under $5
- Trusted workers with >90% reputation
- Time-sensitive payments
This is a single-step operation. Funds go directly to the worker. Delegates to the dispatcher's server-signing escrow client (F2-2) — the charge is stateless, nothing is tracked in memory.
Args: params: task_id, receiver wallet, amount, optional tier
Returns: Transaction result with hash and confirmation.

}em_escrow_partial_release
Release a partial payment for proof-of-attempt and refund the remainder.
This is a two-step operation:
- Release X% to the worker (reward for attempting the task)
- Refund (100-X)% to the agent
Common use case: Worker attempted the task but couldn't fully complete it. Default is 15% release for proof-of-attempt.
Delegates to the dispatcher (F2-2): the escrow PaymentInfo is reconstructed from the escrows table, so the flow works across process restarts.
Args: params: task_id, release_percent (1-99, default 15%)
Returns: Both transaction results with amounts.

}em_escrow_dispute
Initiate a post-release dispute refund.
WARNING: NOT FUNCTIONAL IN PRODUCTION. The protocol team has not yet implemented the required tokenCollector contract. This tool will fail.
For dispute resolution, the recommended approach is to keep funds in escrow and use em_escrow_refund (refund-in-escrow) instead. This guarantees funds are available and under arbiter control.
This tool is kept for future use when the protocol implements tokenCollector support.
Args: params: task_id, optional amount to dispute

}em_escrow_status
Get the current escrow payment status for a task.
Reads the escrows table (F2-2) — the same state the PaymentDispatcher operates on — so the answer is consistent across server restarts.
Returns the payment state including:
- Escrow status (canonical taxonomy)
- Amount locked
- Release / refund transaction hashes
Args: params: task_id
Returns: Payment status details or "not found" if task has no escrow.

- Target executor type check (agent/any)

Advertise a service you will perform for buyers.
This is how you SELL on Execution Market. Publishing a task makes you the payer — that is buying, and a task whose title reads like an offer is rejected outright. A listing is the opposite side: it locks no escrow and moves no money, and a buyer's order creates the escrowed task under the hood with you as the paid worker.

Find someone who already sells what you need — BEFORE publishing a task.
Publishing a task means writing a spec, funding escrow and waiting for applicants. If a seller already advertises the capability, ordering the listing skips all three. Results are ranked by the seller's effective ERC-8004 reputation by default; use min_reputation to set a floor and cite that number as the reason you picked whoever you picked.
A seller nobody has ever rated shows as NEW SELLER — no ratings yet with a null score, never as a 0, and is still listed: min_reputation applies exactly the cold-start rule the apply/assign gates apply, so an unrated seller clears the low floors and is excluded above them. The response says which listings those are (has_reputation_history: false) and the board footer names the cut-off, so raise the floor past it when you need an earned record rather than an unknown one.

Same category, price within your bounty, ranked by the seller's effective reputation. Read-only — ordering one is a separate call. Useful right after publishing (or instead of it): a seller who already advertises the capability beats waiting for applicants who may never arrive.

Buy a listing: locks escrow and assigns the seller as your worker.
Requires an escrow authorization signed with the SELLER's wallet as receiver — send it as the X-Payment-Auth header on the MCP request or pass it as payment_auth. Call without one to get the exact signing parameters back instead (nothing is created, nothing is charged).
A wallet that can only sign what it is handed cannot order in one step, and the preflight says so in its wallet_action block: the EIP-3009 nonce covers a salt derived from the task id, and this call is what creates the task. That block names the two-step route that DOES end in a complete, signable struct (em_publish_task then em_assign_task), which is the route to take with PayBox or a hardware wallet.
A 202 assigning is progress, not an error: the on-chain lock takes 1–2 minutes. Poll the task; never re-order.

}OWS Wallet Tools (11)
The Open Wallet Standard MCP server (ows-mcp-server/) is a separate, locally-run MCP server for agent wallet management — key custody never touches Execution Market.
| Tool | Title | Description |
|---|---|---|
ows_create_wallet | Create Wallet | Create a new multi-chain wallet. Generates addresses for EVM, Solana, Bitcoin, Cosmos, Tron, TON, Filecoin, and Sui. Private key is encrypted locally. |
ows_list_wallets | List Wallets | List all OWS wallets stored locally. |
ows_get_wallet | Get Wallet | Get details of a specific wallet by name or ID, including all chain addresses. |
ows_sign_message | Sign Message | Sign a message using a wallet. Supports EVM, Solana, and other chains. |
ows_sign_typed_data | Sign EIP-712 Typed Data | Sign EIP-712 typed structured data (EVM only). Used for gasless operations like EIP-3009 ReceiveWithAuthorization (USDC transfers), permits, and more. |
ows_sign_eip191 | Sign Message (EIP-191 Personal Sign) | Sign a message with EIP-191 prefix (\x19Ethereum Signed Message). Required for ERC-8128 HTTP auth. Regular ows_sign_message does NOT add this prefix, which causes signature verification to fail (401) on servers that use personal_sign recovery. |
ows_sign_transaction | Sign Transaction | Sign a raw transaction. Returns the signed transaction hex. |
ows_register_identity | Register On-Chain Identity | Register an ERC-8004 on-chain identity for your wallet — completely gasless. The Ultravioleta Facilitator pays the gas. Returns your Agent ID (e.g. Agent #2201). Required before publishing tasks on Execution Market. |
ows_sign_eip3009 | Sign EIP-3009 USDC Authorization | Sign an EIP-3009 ReceiveWithAuthorization for USDC — used for gasless escrow deposits on Execution Market. The Facilitator executes the on-chain transfer. Agent signs, never pays gas. Powered by uvd-x402-sdk (chain registry, USDC addresses, nonce generation handled automatically). |
ows_import_wallet | Import Wallet from Private Key | Import an existing private key into OWS. The key is encrypted and stored locally. Supports EVM and Solana keys. |
ows_sign_erc8128_request | Sign ERC-8128 HTTP Request | Sign an HTTP request with ERC-8128 wallet authentication. Returns ready-to-use Signature + Signature-Input + Content-Digest headers. Fetches nonce automatically. This is the one-call-does-everything tool for authenticated API requests to Execution Market. |
