Amplitude serves an AI Catalog
manifest at /.well-known/ai-catalog.json on amplitude.com, declaring
5 agentic resources
that a discovery service can index without asking anyone’s permission.
Run against this exact body with the project’s own
conformance CLI.
Discovery path
predecessor
Answered only at /.well-known/ai-catalog.json. ARD v0.91 renamed the path to /.well-known/ard.json and made the old one an optional courtesy, so a consumer implementing only the current spec will not find this manifest.
Declared spec version
1.0
The specVersion in the manifest. 1.0 is current for the AI Catalog data model; anything lower is an earlier draft. ARD reads this field as transport-defined and ignores it.
Optional affordances missing. None of these break a client, but each one costs the publisher search relevance or verifiability.

What this manifest advertises
Amplitude MCP Server
urn:air:amplitude.com:mcp:analytics
Read and write Amplitude analytics, taxonomy, and content as tools: charts, dashboards, notebooks, experiments, feature flags, cohorts, session replays, events, and properties. Authenticated with OAuth 2.0; tools inherit the permissions of the authenticated Amplitude user.

“what were the daily active users over the last 7 days”
“show signup conversion rates by traffic source this month”
“should we ship the new onboarding experiment, analyze the results”
“show me session replays where users rage-clicked on the checkout page”
“create a cohort of power users who completed 10 or more sessions in the last 30 days”
Amplitude Docs MCP Server
urn:air:amplitude.com:mcp:docs
Public, read-only MCP endpoint serving Amplitude's English developer and product documentation. No authentication required. Does not access any Amplitude account data.

“how do I initialize the Amplitude Browser SDK”
“what parameters does the Amplitude HTTP V2 API accept”
“search the Amplitude docs for session replay privacy controls”
Amplitude Public APIs

OpenAPI 3.1 description of Amplitude's public HTTP surface: event ingestion, analytics queries, taxonomy management, raw data export, cohorts, and agent-readable site content.
“export raw Amplitude event data for a date range”
“query event segmentation from the Amplitude REST API”
Amplitude MCP Marketplace
urn:air:amplitude.com:skills:mcp-marketplace
Official open-source plugin repository of skills, agents, and commands that extend the Amplitude MCP server: chart and dashboard creation, experiment analysis, session replay debugging, AI agent analytics, analytics instrumentation, and recurring briefings.

How it is served
The publishing guide asks for three things at the transport layer, because a crawler is the
consumer that matters and a crawler is a browser-shaped client.
HTTPS only — yes (HTTP 200)
Content-Type: application/json —
yes
Access-Control-Allow-Origin: * —
yes
Evidence. Fetched https://amplitude.com/.well-known/ai-catalog.json on 2026-09-13, HTTP
200. The verbatim body is stored alongside its manifest in the
Amplitude repository
as ai-catalog/amplitude-ai-catalog.json. Nothing on this page is derived
or generated: an AI Catalog manifest is served from the publisher’s own domain or it does not
exist, which makes it — like an
A2A Agent Card — one of the few agent artifacts that cannot be
produced on a provider’s behalf. Grades are recomputed on every build; the specification is a
v0.9 draft and
these verdicts will move when it does.
Every descriptor here is available over the APIs.io API and to AI agents over MCP. Agent Discovery is not yet its own endpoint on the v1 API. Reach it through catalog search and the tag graph, or the MCP server.
