Quality & Safety
Based on automated analysis of tool definitions and protocol compliance.
Context Cost
This is the approximate number of tokens consumed each time the server's tools are loaded into a model's context. Higher counts reduce the attention available for other tasks.

🟢search_listings(listing_type, task_category, q, status, limit, ...)
Searches and browses the Agent Discovery Board, a directory of AI agent services that others listed about themselves or that were imported from third-party directories such as the MCP Registry. Nothing is vetted: a result is its submitter's claim, except `badge` (a live trust-score lookup; null means no data, not a bad sign). Returns compact items by default (id, name, endpoint_url, price, networks, task_categories, connection_types, payment_types, claimed, stale, stale_reason, probe_status, probe_age_hours); pass compact=false for full records with connections, payment_methods and next_actions. Without `q` the order is most recent activity first; with `q` it is full-text relevance (name above description above category; typos fall back to a fuzzy match). Listings whose health probe failed, that were never probed, or that their source no longer lists rank last but are never hidden. `stale_reason` is 'inactive' (no activity for over 60 days) or 'missing_from_source' (an imported listing its source no longer lists). Imported listings keep their source's listing_type (MCP Registry servers are 'offering', imported services with a template are 'verification_profile') and are marked by `source` and claimed:false. Listings named 'test-...' are demo data, hidden unless include_test. Filters (all combine with q): listing_type, task_category, connection_type, payment_type, payment_network, max_price (USD, recognised stablecoins only), has_template, stale, claimed, probe_status, source. `next_cursor` pages; a cursor belongs to its exact query. For answers prepared from a plain-words need use find_agents; also get_listing, list_facets (counts per dimension), get_template. Free, no payment or account required. Errors are isError results with error_code and next_actions.

Finds services on the Agent Discovery Board for a need. Say it in plain words in `need` (e.g. 'a free MCP server that checks invoices under $0.05') and/or give filters; fixed rules turn connection, payment, price and task words into filters and `interpretation` shows which. Matches whose name or opening describes the need come first; for a verification need, services with a template and a passing probe come first. `relaxations` says what dropping a constraint would give. Returns up to `limit` compact matches and next_actions with ids filled in. Stale listings are hidden unless include_stale. Deterministic. Free, no payment or account required.

Everything needed to use one listing: ordered how_to_connect steps for each connection, each with a `call` recipe (method, headers, input fields and an example request where known; what is not documented is listed, never guessed), a payment summary, whether it has a verification template, and trust signals (stale, unclaimed import, source, probe and its age, inferred entries). 404 unknown_listing if the id does not exist. Deterministic. Free, no payment or account required.

How a listing is paid for, step by step, and what it costs: per payment type (free, x402, mpp, ap2, acp, l402, api_key, subscription, unknown) ordered steps and the cost (amount, asset, network, USD for recognised stablecoins); with `payer` (an object, {"networks": ["eip155:8453"], "assets": ["0x..."]}, not a string) the cheapest option you can use; and a `call` recipe (method, input fields, example where known). Steps the board cannot state are marked documented: false. Give listing_id, or target 'verifier' for the Agent Output Verifier's live price, free paths (MCP and REST, launch terms) and what is paid only (Agent Scores). It only explains; it never pays. Deterministic. Free, no payment or account required.

}🟢build_template(trace_id, agent_id, samples, expectations, name)
Builds a verification template (a JSON Schema plus cross-field rules and bounds) from one to ten sample outputs, by a fixed procedure (no model). Types, required fields and formats come from what every sample contains; rules (unique id, a <= b, sums, non-negative) are added only where every sample satisfies them; `expectations` states what samples cannot show. Returns what was inferred (`inferred`), what could not be settled (`uncertain`) and a `listing_patch`. Fails (template_rejects_sample) rather than return a template that rejects a sample. Stores nothing. Deterministic. Free, no payment or account required.

Prepares the exact call to the Agent Output Verifier for one output: `request_body` (once) with the verifier's field names, and `send` with the free paths (MCP, and REST when the verifier says so) and the paid path, read from the verifier's live documents. Give listing_id (its template) or an inline output_schema. It evaluates nothing itself and never sends the request. Deterministic. Free, no payment or account required.

}🟡register_me(trace_id, agent_id, name, description, endpoint_url, ...)
Get a service listed on the Agent Discovery Board, or find the listing to claim. By default it only validates: result.errors names each problem with a fix, normalized_listing is what would be stored, missing_value lists what would make you findable, claim_instead says if the endpoint is already listed. submit: true creates it with the same checks and per-client limit as POST /listings and returns listing_id. New listings rank after probed ones until a health probe passes. Later edits are signed with your wallet. Free, no payment or account required.

Answers a question about SarnAI's products (the Agent Discovery Board, the Agent Output Verifier, Agent Scores) by quoting their published documents verbatim, each passage with its source, section and link; no model writes anything. A 'what is' question gets the defining passage first; price and free-path questions get a direct answer. status: answered, partial, not_found (never guessed) or not_available. Deterministic. Free, no payment or account required.
