## Quality 75/100 (good)

### protocol: 75 (weight 25)

- warn `protocol.modern`: newest supported version is 2025-11-25; 2026-07-28 not supported, older versions are deprecated until 2027-07-28
- n/a `protocol.stateless`: only applies to 2026-07-28 servers
- pass `protocol.transport`: streamable HTTP
- n/a `protocol.list_ttl`: only applies to 2026-07-28 servers

### 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.token_cost`: about 3,771 tokens to load every tool
- pass `tools.api_dump`: tools are not a one-to-one API dump

### stability: 25 (weight 15)

- warn `stability.changes`: 15 tool changes in 30 days
- fail `stability.rug_pull`: 5 tools kept their name but changed most of their description in 30 days; review before trusting them

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

- Checks run on what our credential-free, read-only probes observe; tools are never called and no code audit is performed.

### Tool changes

- 2026-10-13 `execute` changed (description)
  - before: Run a JavaScript async function in an isolated sandbox, composing catalog_search, model_detail, offer_compare, benchmark_results, provider_list, and benchmark_list as catalog.* methods. Return a small JSON value. Example: async () => { const page = await catalog.catalog_search({query: 'claude', page_size: 5}); return page.data.models.map(m => ({slug: m.slug, prices: m.bestOffer?.prices})); }. No network, secrets, or database binding is exposed. Shared worldwide execution budgets: 100 per UTC minute and 5000 per UTC day. Limits: 30 executions per client per minute (IPv6 /64), 20 catalog calls and read units (offer_compare uses 5), at most two concurrent calls, 5 seconds wall time, 50ms sandbox CPU, 32KiB code, 64KiB JSON output. JavaScript only; no imports or TypeScript syntax. Use /mcp?mode=code for only search + execute.
  - after: Run a JavaScript async function in an isolated sandbox, composing catalog_search, model_detail, offer_compare, benchmark_results, provider_list, benchmark_list, coding_agent_list, coding_agent_detail, coding_agent_releases, coding_agent_upgrade, and price_watch as catalog.* methods. Return a small JSON value. Example: async () => { const page = await catalog.catalog_search({query: 'claude', page_size: 5}); return page.data.models.map(m => ({slug: m.slug, prices: m.bestOffer?.prices})); }. No network, secrets, or database binding is exposed. Shared worldwide execution budgets: 100 per UTC minute and 5000 per UTC day. Limits: 30 executions per client per minute (IPv6 /64), 20 catalog calls and read units (offer_compare and price_watch use 5), at most two concurrent calls, 5 seconds wall time, 50ms sandbox CPU, 32KiB code, 64KiB JSON output. JavaScript only; no imports or TypeScript syntax. Use /mcp?mode=code for only search + execute.
- 2026-10-13 `price_watch` added
  - Read current offers meeting a monthly baseline_usd minus minimum_saving_usd. Uses the same workload, qualifications and evidence filters as offer_compare. Omit model_slugs to watch all qualifying models. Returns up to 50 cheapest matches; no account or delivery subscription is created. The same query is available as RSS at /api/v1/price-watch/feed.xml; your RSS reader handles polling and notifications. Inspect offer warnings before switching.
- 2026-10-13 `coding_agent_upgrade` added
  - Find archived changes published after an installed version or exact release ID. Get agent_slug and source_id from coding_agent_detail; default source_id is primary. Only the same publisher source and recognizable product stream are compared. Stable only by default; use channel all for prereleases. The ready response is publication order, not semantic-version precedence or an upgrade safety assessment; backports may appear. An unknown or ambiguous baseline is explicit in data.status, never treated as no changes. Follow data.pagination.hasMore with offset and limit.
- 2026-10-13 `coding_agent_releases` added
  - Search archived coding-agent releases by agent_slug, query (title, version, excerpt), topic, and channel. Stable only by default; channel all includes prereleases. Newest first; advance offset by limit while pagination.hasMore. Includes source URLs, abbreviated excerpts, and per-agent freshness/coverage. Topics are keyword mentions, not assessments. Partial coverage is explicit in meta.completeness; all unavailable returns an error. Archives reflect configured source history, not every product announcement.
- 2026-10-13 `coding_agent_detail` added
  - Get a coding-agent profile by agent_slug from coding_agent_list, including official source, latest stable release, freshness, and history coverage. An unavailable archive is explicit in state. This does not assert product benchmark rankings or subscription prices.
- 2026-10-13 `coding_agent_list` added
  - List coding-agent profiles, interfaces, model access, official sources, latest stable release, archive counts, freshness, coverage limits, and sourced model/provider compatibility, BYOK, billing and setup facts. Includes agents whose release archive is unavailable; inspect state. Use coding_agent_releases to page through source-linked changelogs.
- 2026-10-13 `offer_compare` changed (description, inputSchema, outputSchema) **meaning changed**
  - before: Rank current provider offers for up to five canonical model slugs by the USD cost of your input/output token workload. Input tokens are uncached. Estimates use base-context rates and exclude long-context tiers, cache writes, batch discounts, and free-tier quotas. provider_slugs restricts the ranked offers.
  - after: Rank current chat offers for up to five canonical model slugs with the website calculator: context-tier prices, cache reads/writes, retries, supported batch rates, capability/benchmark requirements, provider/route preferences, and evidence filters. Input totals include cache shares; cache_hit_percent plus cache_write_percent must be <=100. Average request sizes determine tiers and capacity. Batch is Anthropic direct only. Unknown required evidence excludes offers; missing cache-read rates use standard input rates. Inspect costs, qualification, warnings, assumptions, excludedModels, and pagination.hasMore. Free quotas, non-token fees, and media token accounting are excluded.
- 2026-10-13 `model_detail` changed (outputSchema)

## Packages

_none_

## Tools (12)

- `benchmark_list`: Discover exact benchmark IDs, editions, score units, configurations, provenance, and reviewed result counts before calling benchmark_results. Empty benchmarks are retained with resultCount 0.
- `benchmark_results`: Get reviewed scores for an exact benchmark_id from benchmark_list. Join result.modelId to catalog_search model.id. Compare scores only within the same benchmark edition and configuration. Includes source provenance and reported coding-agent usage when published. Follow pagination.hasMore.
- `catalog_search`: Find canonical model slugs, context limits, and provider prices. Optional provider_slug filters availability, not the provider in bestOffer. bestOffer is selected for 10M input + 2M output tokens; use offer_compare for your workload. Follow pagination.hasMore.
- `coding_agent_detail`: Get a coding-agent profile by agent_slug from coding_agent_list, including official source, latest stable release, freshness, and history coverage. An unavailable archive is explicit in state. This does not assert product benchmark rankings or subscription prices.
- `coding_agent_list`: List coding-agent profiles, interfaces, model access, official sources, latest stable release, archive counts, freshness, coverage limits, and sourced model/provider compatibility, BYOK, billing and setup facts.

- `offer_compare`: Rank current chat offers for up to five canonical model slugs with the website calculator: context-tier prices, cache reads/writes, retries, supported batch rates, capability/benchmark requirements, provider/route preferences, and evidence filters. Input totals include cache shares; cache_hit_percent plus cache_write_percent must be <=100. Average request sizes determine tiers and capacity. Batch is Anthropic direct only. Unknown required evidence excludes offers; missing cache-read rates use standard input rates. Inspect costs, qualification, warnings, assumptions, excludedModels, and pagination.hasMore. Free quotas, non-token fees, and media token accounting are excluded.
- `price_watch`: Read current offers meeting a monthly baseline_usd minus minimum_saving_usd. Uses the same workload, qualifications and evidence filters as offer_compare.
