Reliability, not quality. ``` Scanned 2026-10-21T19:07:04.610Z over streamable-http. **22 tools: 1 do something that can't be undone, 9 change things and 12 only read.** | Group | Class | Tools | Claude Code | | --- | --- | --- | --- | | Deletes or cancels | destructive | 0 | deny | | Can't be undone | irreversible | 1 | ask | | Changes things | write | 9 | ask | | Only reads | read | 12 | allow | ## Findings No check matched anything in these tool definitions. ## Can't be undone (1) Sends, pays, publishes or merges: once done, it cannot be taken back. Claude Code: ask. ### `payment_evidence` - The name "payment_evidence" says "payment": a word that usually means money moves, which cannot be taken back. Description, as the server wrote it: ```untrusted-server-text Payment evidence. PRICED: $0.002 in USDC on base via x402 -- no account, no API key, no invoice. Call without `payment` to receive the exact payment requirements, then call again with `payment` to be served. On-chain payment evidence for one service: how many payments, how many distinct paying wallets, first and last seen. Read off the chain, not off a claim. Counts are per receiving wallet, so one operator on several hostnames shows the same totals on each. ``` ## Changes things (9) Creates or changes something that can be changed back. Claude Code: ask. ### `bulk_export` - Nothing in its name or description says what it does, so it is counted as a write. Description, as the server wrote it: ```untrusted-server-text Cursor-paginated bulk snapshot of endpoints or resources. PRICED: $0.25 in USDC on base via x402 -- no account, no API key, no invoice. Call without `payment` to receive the exact payment requirements, then call again with `payment` to be served. Returns a 1000-record page. Price is per page, not per record. Pass the returned cursor to continue. ``` ### `bulk_score` - Nothing in its name or description says what it does, so it is counted as a write. Description, as the server wrote it: ```untrusted-server-text Bulk scoring. PRICED: $0.02 in USDC on base via x402 -- no account, no API key, no invoice. Call without `payment` to receive the exact payment requirements, then call again with `payment` to be served. Post up to 1000 domains, get one scored row back per row in: score, grade, 90-day uptime, probe count and distinct on-chain payers. The shape an enrichment pipeline expects. ``` ### `cheapest_that_works` - Nothing in its name or description says what it does, so it is counted as a write. Description, as the server wrote it: ```untrusted-server-text Cheapest that works. PRICED: $0.01 in USDC on base via x402 -- no account, no API key, no invoice. Call without `payment` to receive the exact payment requirements, then call again with `payment` to be served. Best value in one capability category: observed price ranked against our own measured uptime. A cheap service that is down is worth nothing, so price alone is not the ranking. ``` ### `gone_dark` - Nothing in its name or description says what it does, so it is counted as a write. Description, as the server wrote it: ```untrusted-server-text Gone dark. PRICED: $0.005 in USDC on base via x402 -- no account, no API key, no invoice. Call without `payment` to receive the exact payment requirements, then call again with `payment` to be served. Services that used to answer and have stopped. Never-alive services are excluded, so this lists things that broke rather than things that never worked. ``` ### `has_it_changed` - Nothing in its name or description says what it does, so it is counted as a write. Description, as the server wrote it: ```untrusted-server-text Change watch. PRICED: $0.002 in USDC on base via x402 -- no account, no API key, no invoice. Call without `payment` to receive the exact payment requirements, then call again with `payment` to be served. Has this endpoint changed since a moment you name. Stateless by design: you pass the time you last looked, we compare it against our probe record. No account and no subscription to administer. ``` ### `new_services` - Nothing in its name or description says what it does, so it is counted as a write. Description, as the server wrote it: ```untrusted-server-text New services. PRICED: $0.01 in USDC on base via x402 -- no account, no API key, no invoice. Call without `payment` to receive the exact payment requirements, then call again with `payment` to be served. Services that appeared recently, roughly 170 a day. New means new to us; a service may predate our first sight of it. ``` ### `preflight_check` - Nothing in its name or description says what it does, so it is counted as a write. Description, as the server wrote it: ```untrusted-server-text Pre-flight check. PRICED: $0.001 in USDC on base via x402 -- no account, no API key, no invoice. Call without `payment` to receive the exact payment requirements, then call again with `payment` to be served. Is this endpoint alive, how long we have known it, what protocols it answers on, what it charges, and whether real money has ever reached it. Answered from our own probe record rather than the service's own claims. First 500 calls a day are free. ``` ### `price_check` - Nothing in its name or description says what it does, so it is counted as a write. Description, as the server wrote it: ```untrusted-server-text Price check. PRICED: $0.001 in USDC on base via x402 -- no account, no API key, no invoice. Call without `payment` to receive the exact payment requirements, then call again with `payment` to be served. What this endpoint charges as we last observed it, not as it advertises, with the live payment terms and whether they match the published ones. ``` ### `uptime_history` - Nothing in its name or description says what it does, so it is counted as a write. Description, as the server wrote it: ```untrusted-server-text Uptime history. PRICED: $0.002 in USDC on base via x402 -- no account, no API key, no invoice. Call without `payment` to receive the exact payment requirements, then call again with `payment` to be served. The 90-day probe record for one service, probe by probe. This is the part nobody who started later can reconstruct. ``` ## Only reads (12) Looks things up and changes nothing. Claude Code: allow. ### `find_tool` - The name "find_tool" says "find": a word for reading. Description, as the server wrote it: ```untrusted-server-text Tool finder. PRICED: $0.002 in USDC on base via x402 -- no account, no API key, no invoice. Call without `payment` to receive the exact payment requirements, then call again with `payment` to be served. Find services by the tools they actually publish, searching the real tool lists of the 6,530 services that expose one rather than their marketing text. ``` ### `get_agent_profile` - The name "get_agent_profile" says "get": a word for reading. Description, as the server wrote it: ```untrusted-server-text Retrieve a full profile for a specific agent or endpoint by its numeric ID or identifier URI. Returns protocol detection, liveness history, on-chain payment evidence, MCP tools list, and A2A skills. FREE for the first 50 calls a day per caller, then $0.02 in USDC on base via x402. Over the allowance, call without `payment` to receive the exact payment requirements, then call again with `payment` to be served. ``` ### `get_demand_preview` - The name "get_demand_preview" says "get": a word for reading. Description, as the server wrote it: ```untrusted-server-text Free preview of the AgentIndex Builder Demand Report: the top three themes builders are asking about right now, with signal counts. The full report -- evidence, supply gaps, release inventory and recommendations -- is the priced tool get_demand_report. ``` ### `get_demand_report` - The name "get_demand_report" says "get": a word for reading. Description, as the server wrote it: ```untrusted-server-text Builder Demand Report: what builders are asking for right now, and where demand has no supply. PRICED: $0.05 in USDC on base via x402 -- no account, no API key, no invoice. Call without `payment` to receive the exact payment requirements, then call again with `payment` to be served. Themes ranked by how often they recur across a nightly-mined corpus of developer questions, forum discussion and search demand, each with the underlying signals as evidence and a stated implication. Crossed against our own measured index to report supply per theme, so a capability that is heavily asked for and rarely built shows up as a number rather than a hunch. Includes a current-version inventory for the main agent protocol projects. Caveats travel inside the payload. ``` ### `get_endpoint_alerts` - The name "get_endpoint_alerts" says "get": a word for reading. Description, as the server wrote it: ```untrusted-server-text Change feed of recently added, changed or newly dark endpoints. PRICED: $0.05 in USDC on base via x402 -- no account, no API key, no invoice. Call without `payment` to receive the exact payment requirements, then call again with `payment` to be served. Returns up to 500 recent endpoint changes, filterable by protocol and time window. Intended to be called repeatedly in place of re-crawling the index. ``` ### `get_liveness_history` - The name "get_liveness_history" says "get": a word for reading. Description, as the server wrote it: ```untrusted-server-text Liveness attestation and retained probe history for one endpoint. PRICED: $0.01 in USDC on base via x402 -- no account, no API key, no invoice. Call without `payment` to receive the exact payment requirements, then call again with `payment` to be served. Probes the endpoint live at request time and returns that alongside the complete retained probe series -- every observation oldest-first, uptime percentage, observed-day count, and each up/down transition with the timestamp it changed and how long the previous state had held. History is a function of elapsed time and cannot be reconstructed after the fact. ``` ### `get_rankings` - The name "get_rankings" says "get": a word for reading. Description, as the server wrote it: ```untrusted-server-text The full ranked table of every scored service. PRICED: $0.25 in USDC on base via x402 -- no account, no API key, no invoice. Call without `payment` to receive the exact payment requirements, then call again with `payment` to be served. Every service we hold probe history for, scored out of 100, ordered best first, each tagged with the categories it leads on. Page with limit and offset. Services we have never probed are absent rather than ranked last, because no history is an absence of evidence, not a bad verdict. ``` ### `get_service_report` - The name "get_service_report" says "get": a word for reading. Description, as the server wrote it: ```untrusted-server-text One-page report on a single indexed service, ending in a verdict. PRICED: $0.02 in USDC on base via x402 -- no account, no API key, no invoice. Call without `payment` to receive the exact payment requirements, then call again with `payment` to be served. Live status, 30 and 90 day uptime computed from our own probe history, advertised price, on-chain payment evidence with distinct payer count, TLS issuer and expiry, the jobs the service declares, and three closest alternatives with their own numbers. Closes with safe / risky / dead and the reason. Every figure cites the table it came from. A domain we do not hold is refused free of charge rather than sold an empty report; check first with the free coverage lookup at /covered/{domain}. ``` ### `get_top_ten` - The name "get_top_ten" says "get": a word for reading. Description, as the server wrote it: ```untrusted-server-text The ten best services in one capability category today. PRICED: $0.02 in USDC on base via x402 -- no account, no API key, no invoice. Call without `payment` to receive the exact payment requirements, then call again with `payment` to be served. Ranked by a score out of 100 built only from what we measured: liveness history over the last 90 probes, on-chain payment evidence, how many independent registries list it, how many protocols it genuinely answers on, and how completely it describes itself. Frozen nightly after the crawl, so every buyer gets the same list for the same day. A service is placed in a category by the names of the tools it publishes and appears in at most three, so the ten lists are genuinely different from each other. ``` ### `get_trust_score` - The name "get_trust_score" says "get": a word for reading. Description, as the server wrote it: ```untrusted-server-text Measured-signal trust score for one endpoint. PRICED: $0.02 in USDC on base via x402 -- no account, no API key, no invoice. Call without `payment` to receive the exact payment requirements, then call again with `payment` to be served. Scores an endpoint on liveness history, on-chain payment evidence, cross-registry corroboration and protocol richness. Every input is independently measured by us; no self-reported field contributes. ``` ### `get_weekly_changes` - The name "get_weekly_changes" says "get": a word for reading. Description, as the server wrote it: ```untrusted-server-text What came alive and what went dark across the whole index in the last seven days. PRICED: $0.05 in USDC on base via x402 -- no account, no API key, no invoice. Call without `payment` to receive the exact payment requirements, then call again with `payment` to be served. Services that started answering and services that stopped, with index-wide totals, over a window you choose up to 30 days. Rebuilt hourly and served identically to every buyer, so it costs the same to read whether you are first or hundredth. ``` ### `search_agents` - The name "search_agents" says "search": a word for reading. Description, as the server wrote it: ```untrusted-server-text Search the AgentIndex for AI agents, MCP servers, A2A agents, and x402-gated APIs by capability keyword. Returns ranked results with type, description, URL, and tags. FREE for the first 50 calls a day per caller, then $0.005 in USDC on base via x402. Over the allowance, call without `payment` to receive the exact payment requirements, then call again with `payment` to be served. ``` ## Claude Code permissions For `.claude/settings.json`, assuming the server is installed as `agent-index`: ```json { "permissions": { "allow": [ "mcp__agent-index__search_agents", "mcp__agent-index__get_agent_profile", "mcp__agent-index__get_demand_preview", "mcp__agent-index__find_tool", "mcp__agent-index__get_liveness_history", "mcp__agent-index__get_trust_score", "mcp__agent-index__get_endpoint_alerts", "mcp__agent-index__get_demand_report", "mcp__agent-index__get_service_report", "mcp__agent-index__get_top_ten", "mcp__agent-index__get_rankings", "mcp__agent-index__get_weekly_changes" ], "ask": [ "mcp__agent-index__preflight_check", "mcp__agent-index__bulk_score", "mcp__agent-index__price_check", "mcp__agent-index__cheapest_that_works", "mcp__agent-index__new_services", "mcp__agent-index__gone_dark", "mcp__agent-index__has_it_changed", "mcp__agent-index__uptime_history", "mcp__agent-index__payment_evidence", "mcp__agent-index__bulk_export" ], "deny": [] } } ```
