Verified MCP Tools: 31,411 tools read from 2,223 live servers

Neuronto Agentic Resource Discovery (ARD) Index · neuronto.com · source

Every MCP registry indexes servers: a name, a URL and whatever prose the publisher wrote. The tool names and input schemas an agent actually has to match on existed in no public corpus. This dataset closes that gap: each row was read from a live server's own tools/list response, not from its marketing description.

What is in it

file	rows	one row is
`tools.jsonl`	31,411	one verified tool: name, description, JSON input schema, and the server it came from
`servers.jsonl`	7,708	one introspection attempt: status, verified tool count, auth requirement, latency
`stats.json`	1	the headline counts and generation timestamp

Headline findings

46% of publicly listed MCP endpoints do not answer a standard initialize handshake (3,547 of 7,708).
1,918 endpoints (24.9%) demand credentials before tools/list, a fact no public registry records.
2,223 servers (29.1%) answered and returned 31,411 tools between them.

How it was collected

Two read-only JSON-RPC calls per endpoint, initialize then tools/list, over streamable HTTP, with a short timeout and no retries. No tool was ever called. Endpoints came from public ARD manifests, the official MCP Registry and public ARD registries. introspection_status records exactly what happened: ok, auth, or error:<kind>.

Why this matters for research

ToolRet (ACL Findings 2025) showed that retrieval models perform poorly at tool retrieval and that this degrades agent task pass rates, but it was assembled from existing datasets rather than the live ecosystem. MCP-Universe (2025) names the "unknown-tools challenge" directly. This corpus is the live ecosystem: real tool names as developers actually write them, real schemas as servers actually serve them, including the truncations, the duplicates and the 400-tool grab-bag servers that clean benchmarks do not contain.

Caveats, honestly

Tool descriptions are authored by their publishers and reproduced verbatim as published interface metadata; quality varies from excellent to promotional.
input_schema is omitted and flagged input_schema_truncated where the stored schema exceeded 8 KB and no longer parsed.
Reachability is a snapshot at verified_at; servers come and go.
A tool's presence here is a statement about reachability and capability, never about trust, safety or quality.

Query the live version

The corpus refreshes continuously. Live search, no key, no signup:
