How this component scores in each security and reliability category. Every signal is checked automatically against the live server, and we only credit what we can confirm. How we score → Why this is hard to score →
Endpoint Security57
- The endpoint's TLS certificate is valid, in date, and uses a strong key. View diagnostics → Pass
- Authorisation check failed: no authorisation is required to call this server, and it exposes a tool marked destructive (delete_saved_search). See how to fix → View diagnostics → Fail
- HTTPS is enforced; there's no plaintext access path. View diagnostics → Pass
- HSTS check failed: the Strict-Transport-Security header is absent. See how to fix → View diagnostics → Fail
- DNSSEC check failed: this domain isn't protected by DNSSEC. See how to fix → View diagnostics → Fail
Transport & Reachability100
- Verified streamable-http transport via a live MCP handshake. View diagnostics → Pass
Schema Quality & AI Usability74
- 100% of prompts and resources have a non-trivial description (not blank, and not just the item's name).Pass
- AI-judged instruction clarity (good).Pass
- Context-footprint check failed: tool/resource definitions use about 34181 tokens (~229/item across 149 items; 141 tools + 8 resources), over budget; trim descriptions and params. See how to fix → Fail
- Usage-examples check failed: none of the tools include examples. See how to fix → Fail
Stability & Change Management100
- No destabilizing schema changes in the last 30 days.Pass
Tool Coverage84
- 100% of tools have a non-trivial description (not blank, and not just the tool's name).Pass
- 53% of tool parameters carry a description.Partial
Tool Safety100
- No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.Pass
- All 2 tool(s) whose name or description implies an irreversible operation declare an MCP destructiveHint annotation.Pass
- An AI judge read all 143 captured unit(s) of tool text and found none that tries to manipulate the model reading it.Pass
Capabilities60
- Spec-recency check failed: implements MCP spec 2025-06-18; the latest is 2026-07-28. See how to fix → Fail
How do I install the io.apis/apis-io MCP server?
io.apis/apis-io is a hosted endpoint at https://apis.io/mcp, so there is nothing to install locally. Ready-made configuration for Claude, Cursor, VS Code, Codex and 5 more is on this page, copied from each client's own documentation.

The tools this component advertises to a client, with an estimated token cost for each. Expand a tool to see its parameters and schema. The per-tool counts are indicative and are not scored directly; the schema's total context footprint is one signal in Schema Quality & AI Usability. A tool's description is untrusted text the model reads on every call, which is what makes this list a security surface and not just an inventory: how tool poisoning works →

agent_readiness_dimensions ~177
UNDERSTANDING — diffusion: for each agent-readiness dimension, how many scored providers satisfy it, out of how many, as a share. The denominator every "the agent web is/is not here yet" claim needs and almost never has. Priced B1 (single-entity synthesis) — $0.01 per call under pay-as-you-go; included in Understanding and Influence. See apis://prices.

apis_io_search ~409
START HERE. Federated overview of the APIs.io catalog for a query: the top matching APIs, providers, AND tags in one call, each with its total match count. Filter by tags, artifact types, industry, region, rating band. `limit` is per section. To page/sort the full list of ONE type, use find_apis / find_providers / find_tags; for one entity, get_api / get_provider.

check_status ~199
INFLUENCE — the status of a check request by id: queued, in_review, running, done, rejected or needs_info, with any notes shared by the reviewer. The id identifies the request, but the Influence plan is now required to read it back. To report an error for free, use report_correction or open an issue on the provider's api-evangelist repo. Priced B1 (single-entity synthesis) — $0.01 per call under pay-as-you-go; included in Understanding and Influence. See apis://prices.

claim_listing ~183
INFLUENCE — ask to claim a listing as yours. Returns 202 with a token and the hosts it will be checked against: publish it as a DNS TXT record, or as a file at /.well-known/apis-io-challenge, and leave it up. A PERSON verifies it and emails you — there is nothing else to call. Track it with check_status. Priced B4 (human work) — worked by a person, no charge. See apis://prices.

cohort_capabilities ~239
UNDERSTANDING — what every member of a cohort actually publishes: artifact counts by type plus the agent-readiness dimensions each one satisfies. The capability matrix behind a market report. Large cohorts come back in byte-budgeted chunks: while `complete` is false, call again with `cursor` set to `next_cursor`; the last page has `complete: true` and a null `next_cursor`. Priced B2 (cross-catalog synthesis) — $0.05 per call under pay-as-you-go; included in Understanding and Influence. See apis://prices.

No output schema declared.
No examples provided.
cohort_failures ~270
UNDERSTANDING — what a whole market gets WRONG: the agent-readiness checks its members most commonly fail, ranked by what fixing each would move the cohort mean. The inverse of gap_analysis, which says where a market is under-served; this says where it is failing the rubric. Turns "fix your OpenAPI" into "this industry does not publish OpenAPI", which is the shape of a finding worth publishing. Named checks only — facet rollups cannot name the checks underneath them. Priced per result — $0.005 per request plus $0.0002 per record returned (less past 100), capped at $0.50 a request, under pay-as-you-go; included in Understanding and Influence. Estimate first at /api/v1/prices/estimate. See apis://prices.

cohort_history ~224
UNDERSTANDING — the SET-LEVEL time series: how a whole market's Kin Score and agent readiness moved, build by build. There was a per-provider series and a whole-dataset licence and nothing between them, so "how has banking moved over six months" had no answer. Returns the MEAN over members present on each date plus members_scored beside it — membership changes as the catalog grows, and a move you cannot attribute to scores rather than population is not a finding. Priced B2 (cross-catalog synthesis) — $0.05 per call under pay-as-you-go; included in Understanding and Influence. See apis://prices.

cohort_rankings ~215
UNDERSTANDING — the leaderboard for a market, on TWO axes: rank by Kin Score composite AND rank by agent readiness. The two orders differ, and the gap between a provider's two ranks is usually the story. Priced per result — $0.005 per request plus $0.0002 per record returned (less past 100), capped at $0.50 a request, under pay-as-you-go; included in Understanding and Influence. Estimate first at /api/v1/prices/estimate. See apis://prices.

cohort_scores ~220
UNDERSTANDING — facet-level scores for every member of a cohort, each with the cohort average and the delta against it. A 60 in governance means nothing until you know the market sits at 45; this is the endpoint that says so. Priced per result — $0.005 per request plus $0.0002 per record returned (less past 100), capped at $0.50 a request, under pay-as-you-go; included in Understanding and Influence. Estimate first at /api/v1/prices/estimate. See apis://prices.

cohort_stats ~253
UNDERSTANDING — the DISTRIBUTION for a whole market: Kin Score mean/median/min/max/stdev, agent-readiness spread, band split, per-facet averages, and artifact adoption rates. This is the market-stats sheet from a Trend Report, computed live. Always carries a `coverage` block saying how much of the roster is actually scored AND how deeply we enriched it (`enrichment_depth`: mean catalog_gap and median artifact directories). Read that before quoting the mean anywhere: cohort enrichment depth spans ~42 points of catalog_gap across the catalog, so part of any cohort number is our coverage rather than the market. Priced B2 (cross-catalog synthesis) — $0.05 per call under pay-as-you-go; included in Understanding and Influence. See apis://prices.

compare_cohorts ~296
UNDERSTANDING — two markets side by side on one rubric: "is US payments further along than UK banking?" Returns both distributions plus the deltas on score, agent readiness, every facet and every adoption rate. A question a written report cannot answer, because a report only ever covers one market. CHECK `depth_confounded` FIRST: when the higher-scoring cohort is also the one we enriched more deeply, the delta reflects our own coverage as much as the markets, and `depth_note` says by how much. Priced per result — $0.005 per request plus $0.0002 per record returned (less past 100), capped at $0.50 a request, under pay-as-you-go; included in Understanding and Influence. Estimate first at /api/v1/prices/estimate. See apis://prices.

correct_facts ~255
INFLUENCE — propose corrections to what we say about you: name, description, url, industries, tags. Returns 202 and is applied by a person — an API that let an owner rewrite their own description unreviewed would be a marketing surface, not a catalog. Score and band are not owner-settable and are ignored. Priced B4 (human work) — included in Influence; otherwise $49.00 as a one-off with its own receipt, never from a prepaid balance. If this is your own company and our data about it is wrong, report_correction is free. See apis://prices.

deprecated_operations ~229
UNDERSTANDING — every provider publishing at least one operation marked deprecated in its own OpenAPI, ranked by how many. The lifecycle view of the catalog: 8,297 deprecated operations across 681 providers, which nothing could see before, because a provider's own deprecated filter needs you to already suspect that provider. Drill in with get_provider_operations(deprecated=true).

export_dataset ~374
LICENCE (sold on the Influence plan) — the WHOLE dataset, not a 100-row page: `ratings` (every rated provider with facets, trend, rubric + provenance), `providers` (the catalog with coverage + score), or `history` (every provider's full score time series — parallel date/composite/agent_readiness arrays across every scored build the catalog retains, with a movement summary per provider). `history` is the one nobody can reconstruct after the fact: it is the only record of what the catalog looked like on those dates. For media outlets and analysts licensing the data to publish rankings and trends. Every dataset exceeds one response, so they arrive in byte-budgeted chunks: while `complete` is false, call again with `cursor` set to `next_cursor` and concatenate `data`; the last page has `complete: true` and a null `next_cursor`. Attribute to apis.io and cite the rubric. Priced B3 (bulk export) — $0.002 per row, $0.50 minimum per call under pay-as-you-go; included in Understanding and Influence. See apis://prices.

find_apis ~734
Paginated, sortable list of APIs across providers — filter by tag, provider, artifact type, industry, region, or rating band. Matching is LEXICAL: `q` searches the API's own name and description. apis_io_search reports a larger API total for the same `q` because it also counts every API belonging to a provider whose NAME matched; pass include=["via_provider"] here to get that same union, and `meta.query.via_provider` says how many rows it added. Use apis_io_search first for a cross-type overview.
