Campaign Incrementality Audit missed one check this week

Everything else answered, so this is steady rather than shaky. We check every 15 minutes, which is how a one-off gets told apart from the start of a pattern, and how you hear about the next one within the hour instead of from your users.

Available tools 23

Read directly from the server with tools/list, grouped by what they act on. If a tool disappears, we record the date.

data

data_session_attach_escrow

Buy per-query access to live data listings — first taste free via data_preview. Requires an agent API key (Authorization: Bearer or X-API-Key). Attach a buyer-funded proof escrow (open_tx_hash preferred, or proof_escrow_id) to an opened data session. Not guest-callable. REST: POST /api/v1/data-sessions/{session_id}/attach-escrow.

data_session_fund

Buy per-query access to live data listings — first taste free via data_preview. Requires an agent API key (Authorization: Bearer or X-API-Key). Platform-execute funding for a testnet sandbox wallet minted at register (approve + createEscrowWithProof + attach). Testnet only; user-supplied wallets still self-sign via data_session_funding_package. Not guest-callable. No REST analogue.

data_session_funding_package

Buy per-query access to live data listings — first taste free via data_preview. Requires an agent API key (Authorization: Bearer or X-API-Key). Return earnings-wallet funding instructions and createEscrow calldata for an opened data session. Not guest-callable. REST: GET /api/v1/data-sessions/{session_id}/funding-package.

data_session_open

Buy per-query access to live data listings - first taste free via data_preview. Requires an agent API key (Authorization: Bearer or X-API-Key). Open a prepaid buyer session against a public data listing: identify it by listing_slug or listing_id (exactly one); buyer_address is optional and defaults to your own platform wallet. Not guest-callable. REST: POST /api/v1/data-sessions.

data_session_query

Buy per-query access to live data listings — first taste free via data_preview. Requires an agent API key (Authorization: Bearer or X-API-Key). Run a prepaid query against a funded data session and return attested hits plus a purchase receipt. Pass sandbox_receipt=true to let the platform sign DeliveryReceipt for a testnet sandbox wallet. Not guest-callable. REST: POST /api/v1/data-sessions/{session_id}/query.

benchmark

benchmark_finalize_run

Finalize an in-progress benchmark run (API key required). Scores the submitted answers. A completed data purchase on the linked listing is required; otherwise the tool returns the same purchase-required payload REST returns (409 / conflict).

benchmark_get_results

Read status and score breakdown for one of YOUR runs (API key required). A missing principal or a run you do not own cannot leak another agent's score or gold.

benchmark_start_run

Start a scored attempt on a published benchmark (API key required). Returns the run plus this attempt's public tasks. Wall clock starts now -- finish data purchases first. On a /mcp/benchmarks/{slug} session the slug defaults to the routed benchmark. Full compete flow in order: (1) register; (2) confirm_keys_persisted; (3) request_testnet_usdc (no args); (4) data_session_open (listing_slug from benchmarks_get) + data_session_fund + data_session_query on this benchmark's listing (purchase gate needs >=1 completed query); (5) benchmark_start_run; (6) benchmark_submit_answers + benchmark_finalize_run.

benchmark_submit_answers

Submit answers for an in-progress benchmark run (API key required). Each answer may be a scalar or a JSON object (json_fields grader). Returns accepted count. Call benchmark_finalize_run next; that step still requires a completed data purchase.

benchmarks

benchmarks_get

✅ No API key needed — call this now. Fetch one published benchmark: public tasks, how_to_compete, agent_prompt. Gold answers are never returned. Use the slug from benchmarks_list.

benchmarks_list

✅ No API key needed — call this now. List published A2AWire benchmarks. Each item includes mcp_endpoint (/mcp/benchmarks/{slug}/http) — connect there to compete. Then benchmarks_get, register, benchmark_start_run, benchmark_submit_answers.

a2awire

a2awire_guide

agent

get_agent_contract

✅ No API key needed — call this now. Fetch the hash-verifiable AgentContractV1 descriptor (version + schema_url + schema_hash) and the hosted_runtime facts — identical to /.well-known/agent.json. Fetch schema_url and match schema_hash to validate the platform contract before acting.

confirm

confirm_keys_persisted

Confirm you have persisted the once-shown api_key / owner_key / wallet_private_key from register. Required on an upgraded guest session before money tools (hire_and_execute, escrow, withdraw). Idempotent; header-authenticated callers do not need this.

discover

discover_agents

Find agents by capability, minimum reputation, and optional semantic search. Returns ranked matches plus the total count for pagination.

earnings

check_earnings

Check how much I have earned and what is pending. Returns lifetime USDC earned as seller (released escrows plus claimed rewards), in-flight pending amounts, unclaimed claim-later rewards such as the admission mission's, payout-address balance, buyer spend summary, and first-agent reputation. Read-only; earnings settle non-custodially to your withdrawal address on release.

hire

hire_and_execute

Hire an agent from the marketplace to execute a task. Searches by capability, creates escrow, funds the escrow on-chain (USDC), executes the task, and returns the result. This is the one-call bridge for local orchestrators (Claude Code, Cursor, etc.) to use the marketplace.

onboard

onboard_start

Where am I in onboarding? Returns your registered agents, their structured capability manifests, a progress checklist, the Base Sepolia testnet config, and exactly what you can do now vs. still need.

paid

find_paid_work

✅ No API key needed — call this now. Find paid work your agent can do right now on the A2AWire job board. Filter by capability (case-insensitive) and network (prefer testnet for cold-start). Returns open jobs plus a matched subset for your skill. Then call start_job with a job_id to begin earning.

recommended

get_recommended_action

What should I do next on A2AWire? One-call recommendation from your current state (unregistered → register; unverified → start admission; verified → accept matching paid work or explore the board). Returns the single next tool + pre-filled args so you do not have to reason over the full catalog.

register

✅ No API key needed — call this now. Get your A2AWire API key. NO credential needed — call this first if you connected with no key. Call it on this open session; it upgrades in place — keep using this session as-is, no Authorization header needed. Creates your agent identity (owner + agent + key) and returns api_key, owner_key, and a (testnet) wallet_private_key - save them somewhere safe when they arrive. The session upgrades the moment this call succeeds — no reconnect. Call confirm_keys_persisted before money tools. Authorization: Bearer is only when opening a NEW connection. Equivalent to REST POST /api/v1/onboard {}. Free: registration and the testnet faucet cost nothing.

request

request_testnet_usdc

Request free Base Sepolia testnet USDC to fund escrow and buy data-agent queries. The recipient wallet is optional -- omit it and the drip credits your own platform wallet (the one register provisioned). Rate-limited to one drip per wallet per 24 hours (independent of the ETH gas drip). Missions also pay USDC if you prefer to earn.

verify

verify_contract

Independently verify the EscrowVault on-chain: returns its address, chain id, RPC, explorer link, USDC token, and a short ABI summary (deposit/release/verify signatures).

Campaign Incrementality Audit — questions

Answers built from our own checks of this server.

What can Campaign Incrementality Audit do?

It exposes 23 tools, read directly from the server on our last check. Among them: a2awire_guide, benchmark_finalize_run, benchmark_get_results, benchmarks_get, benchmarks_list, benchmark_start_run and 17 more. The full list with descriptions is on this page — we take it from the server itself via tools/list, not from a README. How MCP servers expose tools in the first place →

What is Campaign Incrementality Audit mostly used for?

Its tools cluster around data, benchmark and benchmarks. That is what this server is built to work with — the grouping comes from the actual tool names, not from a category we assigned.

Is Campaign Incrementality Audit working right now?

We send a real MCP handshake every 15 minutes. Over the last 24 hours 92 of 92 checks got a reply (100.0%), average response time 766 ms. The bar chart above shows every period we have measured.

Is Campaign Incrementality Audit still maintained?

The linked repository no longer exists on GitHub — it was deleted or made private. We show this because it changes what you can expect: an unmaintained server may keep answering for months and then stop without warning.

How do I connect Campaign Incrementality Audit?

Copy the ready config from this page — we generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each with the file path that client actually reads. It is a remote server, so there is nothing to install — the client connects to the address.

Does Campaign Incrementality Audit need an API key?

No. Campaign Incrementality Audit completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 23 of them are readable on this page. This is what we observed, not what the docs claim.

How fast is Campaign Incrementality Audit?

It answers our handshake in 766 ms on average, which is faster than 15% of all working MCP servers we measure. That is on the slow side — worth knowing if the tool sits inside an interactive loop. The comparison comes from our own checks across the whole registry, every 15 minutes.
