## Quality 88/100 (good)

### protocol: 75 (weight 25)

- pass `protocol.modern`: supports 2026-07-28 (server/discover)
- warn `protocol.stateless`: requires a session despite supporting 2026-07-28
- pass `protocol.transport`: streamable HTTP
- warn `protocol.list_ttl`: tools/list carries no ttlMs, so clients re-fetch it

### authorization: n/a (weight 15)

- n/a `auth.prm`, `auth.as_metadata`, `auth.cimd`: no remote uses OAuth
- n/a `auth.secret_in_url`: no templated URL

### tool hygiene: 100 (weight 30)

- pass `tools.descriptions`: every tool has a description
- pass `tools.description_length`: descriptions are concise
- pass `tools.schemas`: every tool has an object input schema
- pass `tools.annotations`: 17 of 17 tools declare readOnlyHint or destructiveHint
- pass `tools.directory_hints`: every tool declares readOnlyHint, destructiveHint, idempotentHint and openWorldHint
- pass `tools.token_cost`: about 1,827 tokens to load every tool
- pass `tools.api_dump`: tools are not a one-to-one API dump
- pass `tools.hidden_text`: no hidden text in tool names, descriptions, schemas or annotations

### stability: 83 (weight 15)

- warn `stability.changes`: 8 tool changes in 30 days
- pass `stability.rug_pull`: no tool changed its meaning under the same name
- pass `stability.new_links`: no tool change named a new site

### dependencies: n/a (weight 15)

- n/a `deps.known_vulns`, `deps.mcp_sdk_version`, `deps.resolvable`: no npm or PyPI package

- tools: 17, about 1,827 tokens to load them all
- tool set hash: 84a22dfd58034d69344263bdd5b4afbe
- tools last changed: 2026-11-09T01:08:17.288Z
- badge: [![protogrid quality](https://protogrid.dev/badge/com.dejabars/pattern-search.svg)](https://protogrid.dev/servers/com.dejabars/pattern-search)
- Checks run on what our credential-free, read-only probes observe; tools are never called and no code audit is performed.

### Tool changes

- 2026-11-09 `analytics_run` added
  - Run and save a full Outcome Lab analysis from a quoted spec. This spends tokens; call analytics_quote first and pass its offer_id.
- 2026-11-09 `analytics_config_delete` added
  - Delete one saved analytics config draft owned by the user.
- 2026-11-09 `analytics_config_save` added
  - Save a named analytics config draft. Pass config_id to update an existing draft; omit it to create a new one. Saving is free and does not create a snapshot.
- 2026-11-09 `analytics_config_list` added
  - List the user's saved Outcome Lab config drafts, optionally for one report.
- 2026-11-09 `analytics_fast_verify` added
  - Run the free fast verification over the first 200 matches. It returns a snapshot and never saves an analysis or charges tokens.
- 2026-11-09 `analytics_quote` added
  - Validate a spec and return the runtime token price, cohort estimate, work units and offer_id. Quotes do not spend tokens.
- 2026-11-09 `analytics_report` added
  - Return one search report, its default analytics spec, ready question configs, suggestions and the estimated cohort. Use report.defaults.spec as the starting config.
- 2026-11-09 `analytics_schema` added
  - Return the analytics metric catalogue, dimensions, curated questions, pricing tiers and fast-verification limit. Start here before building a config.

- `search_status`: Report whether a submitted search is running or complete. A completed search carries its match count and a report_url link to the full human-readable report.
- `search_submit`: Submit a chart-pattern search. Returns a task id immediately; poll search_status/search_result. Idempotent per request within a session only by the caller's own retry discipline.
