No key. ``` Scanned 2026-10-21T18:54:40.579Z over streamable-http. **8 tools: 5 change things and 3 only read.** | Group | Class | Tools | Claude Code | | --- | --- | --- | --- | | Deletes or cancels | destructive | 0 | deny | | Can't be undone | irreversible | 0 | ask | | Changes things | write | 5 | ask | | Only reads | read | 3 | allow | ## Findings No check matched anything in these tool definitions. ## Changes things (5) Creates or changes something that can be changed back. Claude Code: ask. ### `changes_since` - 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 What changed in the tool economy since a date: verdict flips, deaths, revivals, new servers, confirmed drift — the census diff as data. Poll this weekly to keep a local view current without re-crawling. ``` ### `check_server` - 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 The FULL evidence behind the verdict for ONE server, by exact registry name — call should_i_use first for the one-word decision; call this when you want the whole record. Leads with the verdict (allow/warn/block), then the `rating` grouped as REACH (answers, latency vs population, protocol, auth), USE (tool count vs population, capability breadth, harness readiness) and TRUST (costume-farm?, duplicate inventory?, verifiability grade, drift / rug-pull, and where checkable whether its ANSWERS are true vs a public primary), a cluster tag, a distinctiveness score, and an explicit not_claimed block. Argument: name. ``` ### `registry_pulse` - The description's first verb is "call": a word for a change. Description, as the server wrote it: ```untrusted-server-text Call this FIRST for the state of the MCP tool ecosystem in one shot: how many servers exist, how many actually answer a real handshake, how many are behind a login, the largest costume-farm concentration, AND the Tier-2 truth summary (how many server answers were re-derived against a public primary source and matched). Every number is re-derivable; grades observed/reported/derived. No arguments. ``` ### `report_call` - The name "report_call" says "call": a word for a change. Description, as the server wrote it: ```untrusted-server-text AFTER your agent calls a tool, fire-and-forget how it went — success/failure, latency, cost — so the observatory accumulates realized reliability (the one thing outside-in probing can't see: did it actually work for a real call). Anchored against our own probe: a 'worked' report on a server we saw dead is discarded. Does NOT change the current rating yet (probing stays load-bearing) — this is accumulate-ahead-of-demand. Args: server (required), tool, ok, latency_ms, cost_tokens, call_hash (a hash binding the report to a real call). ``` ### `should_i_use` - 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 THE GATE — call this before your agent depends on a tool you don't already trust. Give an exact server registry name and get a one-word verdict — allow / warn / block — with the reason, plus the full rating underneath. 'block' = dead/unreachable/costume-farm-shaped, don't depend on it; 'warn' = usable but look first; 'allow' = safe to depend on. If you have a NEED not a name, use find_tools; if you have a fuzzy name, use resolve_server_name. Argument: name, e.g. 'com.trimtabist/us-tariff-ledger'. ``` ## Only reads (3) Looks things up and changes nothing. Claude Code: allow. ### `find_tools` - The name "find_tools" says "find": a word for reading. Description, as the server wrote it: ```untrusted-server-text Find and RANK the trustworthy tool for a NEED. Describe the task in plain words ('screen a company for sanctions', 'US tariff data', 'vessel tracking') — the search is full-text over tool names AND their stored descriptions (stemmed, BM25-ranked), so your words need not appear in any tool's name. Servers come best-rated first, and EACH ROW carries its verdict (allow/warn/block), cluster, distinctiveness and the matching tool names, so you can pick without a second call. Alive, non-costume, current-protocol servers rank on top; dead / costume-farm / walled ones sink. Argument: need. ``` ### `list_findings` - The name "list_findings" says "list": a word for reading. Description, as the server wrote it: ```untrusted-server-text The observatory's ruled findings — each with its claim and its falsification test — plus the public corrections log (what we published, then corrected, never deleted). Call this to cite what has been established, or to see where we were wrong. No arguments. ``` ### `resolve_server_name` - The name "resolve_server_name" says "resolve": a word for reading. Description, as the server wrote it: ```untrusted-server-text Resolve a partial or misspelled server name to its EXACT registry id before calling should_i_use / check_server. Matches a fragment against registry NAMES only (not capabilities — for 'which tool does X' use find_tools). Returns candidate exact names with each one's latest liveness outcome. Empty query rejected. ``` ## Claude Code permissions For `.claude/settings.json`, assuming the server is installed as `verifier`: ```json { "permissions": { "allow": [ "mcp__verifier__find_tools", "mcp__verifier__resolve_server_name", "mcp__verifier__list_findings" ], "ask": [ "mcp__verifier__registry_pulse", "mcp__verifier__should_i_use", "mcp__verifier__check_server", "mcp__verifier__report_call", "mcp__verifier__changes_since" ], "deny": [] } } ```
