Tools have disappeared from this server

A tool that vanishes takes a piece of your agent with it, and the change arrives silently. Watch this server and every such change lands in your inbox.

Available tools 83

Read directly from the server with tools/list, grouped by what they act on. If a tool disappears, we record the date.

company

company_dimensions

PRO — a company's investment dimensions, each read AGAINST the measured cohort: the cohort median, mean and max, this company's rank and percentile, and an index where 1.0 is exactly typical. A raw dimension score is unreadable on its own; these are the columns that make it mean something.

company_gaps

A company's weakest investment dimensions — where it is thin. Pro.

company_peers

PRO — the companies most comparable to this one (same sub-sector where the data supports it, same industry otherwise), each with signal totals and top dimensions. The response says which basis it used.

company_signals

PRO — the company's adopted stack entity by entity (services, tools, standards), each with how many companies across the cohort carry it and its radar ring.

company_whitespace

PRO — what this company's peers run that it does not, ranked by how many peers carry it. The opening list for a vendor selling into the account.

find_company_insights

Browse profiled companies (Fortune 1000 + API providers) by name; ranked by technology-readiness signal. Free.

get_company_insight

Full demand-side profile for one company: 40-dimension readiness, adopted stack, per-quarter history. Pro.

api

api_coverage

Measure how much of an API description your governance actually inspects — coverage by section, each rule's reach, and the rules that match nothing. Like test coverage, one altitude up.

api_scorecard

Score an API's maturity 0-100 with a letter grade across design, governance coverage, documentation, and (from an apis.json) discoverability, agent-readiness, and operations. Pass your own `ruleset` — a score against rules you never adopted means little.

search_api_evangelist

Unified search across the whole network: 5k+ stories, 77 topic areas, 2.5k governance building blocks, papers, conversations, videos, tools, timelines, services, and vocabulary. Filter with types (posts, areas, guidance, rules, policies, standards, strategies, schema, properties, experiences, lifecycle, conversations, videos, papers, services, solutions, tools, timelines, vocabulary).

standard

standard_adoption

How far a standards body actually got: repositories published, how many graduated past unclassified and the resulting share, release cadence, contributor count — with the provenance of every figure and an explicit list of what is NOT measured. Free, because a specification is a public good.

standard_coalition

Who is actually behind a standard: the governing bodies and their membership, the working groups, the member companies, and the named people. Carries the caveats where our machine-readable source disagrees with the body's own published roster. Free.

standard_repositories

Every repository a standards body publishes, with maturity, stars, forks, open issues and archived status. Free.

validate

validate_api

Lint an OpenAPI, AsyncAPI, Arazzo, or JSON Schema document against the curated best-of-breed ruleset (Spectral) and return the findings. Pass your own `ruleset` to run rules you own instead of the catalog — which is what you should do before gating on anything.

validate_onboarding

Validate an API Onboarding Descriptor (AID) against the api-commons schema and report which optional sections it fills in.

validate_ruleset

Check that an OpenLint/Spectral ruleset is valid BEFORE running or storing it: invalid JSONPath, unknown functions, undefined aliases, and anything the engine rejects. Catalog metadata (title, prompt, x-*) is set aside and reported. Run this on every ruleset you write.

building

find_building_blocks

Search the governance building blocks by type: guidance (177), rules (617), policies (283), standards (432), strategies (75), schema (11), properties (790), experiences (46), lifecycle (29).

get_building_block

One building block by type + slug; include=["content"] returns the full body.

insights

insights_adoption

Services, tools, or standards ranked by how many companies adopt them. Free.

insights_dimensions

Cross-section ranking of the 40 tracked investment dimensions (AI, cloud, governance, …) by company signal. Free.

org

get_org_ruleset

PRO — Read your org default ruleset: the one every governance call without its own `ruleset` runs against.

set_org_ruleset

PRO — Store an org default ruleset (validated first). From then on validate, coverage, scorecard, estate, baseline, codefirst and fix use it whenever no `ruleset` is passed.

apply

apply_overlay

Apply an OpenAPI Overlay to a document and report what each action matched. Use it for deprecation and migration choreography without forking the contract.

area

get_area

One topic area with its related-area graph resolved — walk the network from here.

areas

find_areas

The 77 focused topic areas of the network (agents, gateways, security, …), each a subsite with its own catalog.

audit

audit_pipeline

Score a repository's Spectral CI setup against an 8-point maturity rubric and return a prioritized punch-list. Pass a public `repo` ("owner/name") or `files`.

baseline

baseline_violations

PRO — Adopt a ruleset on a legacy API without a wall of red: snapshot today's violations as a baseline, then pass that baseline back to fail only on NEW violations (with fixed counts, a warning budget and burndown).

certify

certify_api

Issue a tamper-evident governance certificate attesting an API passed a named ruleset at a profile threshold. A SHA-256 fingerprint lets anyone re-verify it.

classify

classify_api_fields

Inventory the PII, secret, and sensitive fields an OpenAPI exposes, across parameters and request/response schemas. Run this before exposing an API to agents.

code

code_snippets

Generate runnable curl, JavaScript, and Python samples for every operation, with path params filled in and a realistic body.

contact

get_contact

Every way to reach API Evangelist — email, contact form, newsletter, GitHub, social channels, and postal mail.

conversation

get_conversation

One conversation with guest detail and media links; include=["content"] returns the writeup.

conversations

find_conversations

API Evangelist Conversations — recorded discussions with API practitioners (guest, company, YouTube/SoundCloud links).

deprecation

deprecation_posture

Report every deprecated operation and whether it actually announces a sunset. The ones that go quiet are the ones that break consumers.

describe

describe_rule

Look up one rule by id — description, severity, given/then, reference — and its remediation prompt: what to change when it fires. Suggests close matches for an unknown id.

detect

detect_format

Identify a document: OpenAPI (Swagger 2.0 vs 3.x), AsyncAPI, Arazzo, JSON Schema, APIs.json, MCP, an agent SKILL.md, an Overlay or a ruleset — and how many catalog rules and which named profiles apply.

diff

diff_api_versions

Compare two OpenAPI versions and classify every change as breaking, non-breaking, or an addition — at path, operation, parameter, request-body, and response granularity.

document

document_ruleset

Generate human-readable Markdown documentation for a ruleset — each rule's severity, what it checks, its message and how to fix it. Pass `ruleset`, or `profile` for a curated one (owasp, problem-details, fhir, api-authorization).

entities

find_entities

Browse the demand-side entity catalog — every service, tool and standard companies are measured against, ranked by how many carry it. Free. This is the left-hand side of the inversion: pick an entity here, then call entity_demand to see WHO.

entity

entity_demand

PRO — THE INVERSION. Every other insights tool runs company -> stack; this one runs stack -> companies: which companies show demand for a given service, tool or standard, broken down by industry. This is the prospecting query — "who should I be selling this to" — and it exists in no report, bundle or page. Returns BOTH the authoritative company count and the companies it can actually name, with the basis difference explained.

explain

explain_rule_result

Explain why a rule did or did not fire on a document: whether its formats matched, what its `given` matched, what `then` checked, and the verdict. Works for your own rules, the catalog, and the built-ins.

export

export_agent_rules

Turn a governance ruleset into agent-native guidance — an AGENTS.md block, a system-prompt set, a per-rule remediation pack, and a digest — so agents follow the rules while authoring, not after linting.

federate

federate_rulesets

PRO — Model a central baseline ruleset and the domains that adopt it (inherit / override / waive / defer / local rules) and compute divergence per rule, drift per domain, and local rules worth promoting.

feeds

get_feeds

The static machine-readable feeds every network site publishes (JSON, APIs.json, zero-auth) — the no-key alternative to this API.

fingerprint

fingerprint_generator

PRO — For a code-first API: identify which OpenAPI generator produced the spec, and split findings into those to fix with code annotations vs. spec authoring, with per-generator remediation.

fix

fix_diagnostics

PRO — Propose an OpenAPI Overlay that fixes the lint errors (or the `rules` you name), apply it, re-lint, and report what was resolved, what newly fires, and any breaking change. Review the overlay before applying it.

forge

forge_mcp_tools

From an OpenAPI, forge an MCP server design, per-operation tools, Agent Skills, an enriched OpenAPI, a server.json, and apis.json properties.

gate

gate_agent_context

Choose which operations and fields an API exposes to agents and emit a governed Tyk OpenAPI, an MCP tool manifest, and a Spectral ruleset with PII and secret checks.

generate

generate_agent_descriptor

Generate an API's llms.txt and an AGENTS.md consumption contract — base URL, auth, the operation table, deprecated operations to avoid, and usage rules.

govern

govern_estate

PRO — Run the core governance checks across a WHOLE SET of internal APIs and roll them up: per-API score/grade/errors/PII, plus estate aggregates (avg score, grade distribution, APIs with PII/secrets) and a worst-first punch-list of what to fix. Pass `apis` ([{id, document}]) and your own `ruleset`. detail:true adds per-API dimensions.

governance

governance_report

Turn Spectral findings into a self-contained HTML governance report — severity summary, grouped by rule, framed toward progress.

guidance

get_guidance_section

One editorial guidance section as a list: history, technology, business, politics, governance, or evangelism — the six lenses API Evangelist organizes guidance through.

guide

guide_topic

PRO — Curated guide to one API topic (e.g. "gateways", "api governance", "discovery", "agents"). Bundles the matching topic area (with related areas), top guidance, rules, policies, and standards, relevant papers and recent stories, plus the API Evangelist services that can help a team with this topic.

jsonpath

query_jsonpath

Evaluate a JSONPath (a rule's `given`) against a document and return what it matches — pointers, values, and optionally whether `field` is present on each match. The fastest way to get a `given` right.

lint

lint_agent_skill

Lint an agent SKILL.md (markdown with YAML frontmatter) against the API Commons skill rules — name, description, structure, metadata.

map

map_api_experience

Map each REST operation to its MCP tool and Agent Skill — the API -> MCP -> Agent-Skill chain — from an APIs.json, with a free/paid coverage scorecard and a flow map.

measured

find_measured_standards

The standards bodies API Evangelist has actually MEASURED — repositories, maturity, governance, coalition. Distinct from find_standards, which searches 613 catalog entries describing what a standard IS. Free.

mock

mock_payloads

Generate an example request and success-response payload for every operation from its schema.

overview

get_overview

START HERE. What the API Evangelist network offers: sixteen years of API research as searchable stories, 77 topic areas, governance building blocks (guidance, rules, policies, standards, strategies), papers, conversations, and the consulting services Kin Lane offers teams. Returns counts, entry points, and how to engage.

paper

get_paper

One paper with its full outline and purchase/landing URL.

papers

find_papers

API Evangelist papers — single-PDF deep dives on one practice or topic, with outlines.

post

get_post

One story by slug (YYYY-MM-DD-slug); include=["content"] returns the full markdown body.

posts

find_posts

Search or browse 5,100+ API Evangelist stories (2010–present); filter by year or tags.

reconcile

reconcile_waivers

Reconcile a waivers file against lint output: suppress sanctioned violations and surface the expired, stale, and expiring ones. Returns the effective failing set a build should gate on.

find_related

Given any doc (type + slug), the most related content across the whole network, ranked by shared-tag relevance (rare, specific tags weigh most). "More like this," across stories, areas, guidance, papers, conversations, and more.

ruleset

ruleset_from_style_guide

PRO — Turn a prose API style guide into an owned, grounded ruleset: one rule per checkable statement, each validated, with the statements no rule can check listed separately. Test the result with test_ruleset.

score

score_reusability

Score how reusable a set of APIs is and detect duplication across them — the anti-sprawl view of an estate.

service

get_service

Full detail for one service offering by slug; include=["content"] inlines the full pitch.

services

find_services

The services API Evangelist offers teams and customers — API strategy, governance, discovery, and evangelism engagements by Kin Lane. The front door to working with API Evangelist. (For the third-party vendor registry, use find_solutions.)

solution

get_solution

One solution from the vendor registry by slug, with its website and adoption count.

solutions

find_solutions

The solutions registry — 740+ third-party API services and tools (gateways, portals, testing, monitoring, …) ranked by adoption across the companies API Evangelist tracks.

stats

get_stats

PRO — catalog intelligence: per-type counts, stories-per-year, and the top tags by reach across the network.

submit

submit_api_evangelist_feedback

Report something wrong with a result: wrong data, a filter that did not filter, a ranking that put off-topic results first, a number you could not reproduce, or an answer that was useless for your task. Free, and the fastest way to get a defect fixed — the support sweep reads the log this lands in. Say what you expected as well as what you got.

tag

get_tag

One tag with its per-type counts and everything it labels across the whole network (stories, areas, guidance, papers, …). Filter with types.

Tools removed

API Evangelist — questions

Answers built from our own checks of this server.

What can API Evangelist do?

It exposes 83 tools, read directly from the server on our last check. Among them: api_coverage, api_scorecard, apply_overlay, audit_pipeline, baseline_violations, certify_api and 77 more. The full list with descriptions is on this page — we take it from the server itself via tools/list, not from a README. How MCP servers expose tools in the first place →

What is API Evangelist mostly used for?

Its tools cluster around company, validate and standard. That is what this server is built to work with — the grouping comes from the actual tool names, not from a category we assigned.

Is API Evangelist working right now?

We send a real MCP handshake every 15 minutes. Over the last 24 hours 91 of 91 checks got a reply (100.0%), average response time 354 ms. The bar chart above shows every period we have measured.

Did API Evangelist ever remove tools?

Yes. find_reports, get_report are no longer exposed — we recorded the date each one disappeared. A tool vanishing usually means a breaking change for anything that depended on it.

Is API Evangelist still maintained?

The linked repository no longer exists on GitHub — it was deleted or made private. We show this because it changes what you can expect: an unmaintained server may keep answering for months and then stop without warning.

How do I connect API Evangelist?

Copy the ready config from this page. We generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each in the form that client actually reads. It is a remote server, so there is nothing to install — the client connects to the address.

Does API Evangelist need an API key?

No. API Evangelist completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 83 of them are readable on this page. This is what we observed, not what the docs claim.

How fast is API Evangelist?

It answers our handshake in 354 ms on average, which is faster than 39% of all working MCP servers we measure. The comparison comes from our own checks across the whole registry, every 15 minutes.
