Search MCP servers ranked by measured handshake checks, tool lists and signed reports.

The com.openforallofus/agora MCP server provides search for MCP servers. Its description indicates that it returns results based on measured handshake checks, tool lists, and signed reports. The server is intended for discovery of other MCP servers using those specific evaluation inputs.

🛠️ Key Features

Search MCP servers
Ranked by measured handshake checks
Uses tool lists for ranking
Uses signed reports for ranking

🚀 Use Cases

Find MCP servers that meet specific measured handshake criteria
Compare MCP servers by available tool lists
Review MCP server entries supported by signed reports

⚡ Developer Benefits

Enables developer-facing discovery based on handshake measurements and reported tool availability
Supports evaluation through signed reports

⚠️ Limitations

Only describes search and ranking criteria; no additional tool functionality is specified

Captured live from the server via tools/list.

search_tools

Search the catalog of MCP servers (from the official MCP registry). Results are ranked by match and by signed proof reports: each signed 'works' report lifts a server, each 'broken' or 'unsafe' one pulls it down.

Parameters2

query	string	required	Words to look for in the server name, title and description
limit	integer	optional

Raw schema

{
  "type": "object",
  "properties": {
    "query": {
      "type": "string",
      "minLength": 2,
      "maxLength": 200,
      "description": "Words to look for in the server name, title and description"
    },
    "limit": {
      "default": 10,
      "type": "integer",
      "minimum": 1,
      "maximum": 50
    }
  },
  "required": [
    "query"
  ],
  "$schema": "https://json-schema.org/draft/2020-12/schema"
}

get_tool

Return one MCP server from the catalog by its exact registry name (e.g. io.github.owner/repo), with every signed proof report filed about it. Report level 'operator-signed' means the operator's gate signed that it allowed a call to the named tool; it does not yet prove which server answered.

Parameters1

name

string

required

Exact registry name, as returned by search_tools

Raw schema

{
  "type": "object",
  "properties": {
    "name": {
      "type": "string",
      "minLength": 3,
      "maxLength": 300,
      "description": "Exact registry name, as returned by search_tools"
    }
  },
  "required": [
    "name"
  ],
  "$schema": "https://json-schema.org/draft/2020-12/schema"
}

submit_report

Report that a catalog server works, is broken or is unsafe, backed by a signed decision record (Cedulon format) from your gate. The record must verify under the public key you send, its decision must be 'allow', and each record can back only one report. Unsigned opinions are not accepted here.

Parameters5

server	string	required
verdict	string	required
note	string	optional
receipt	object	required
operatorKeyPem	string	required	PEM public key of the gate that signed the record

Agora by openforallofus

Search for MCP servers, ranked by what was measured instead of what was voted.

Live at https://openforallofus.com. Agents can use it directly as an MCP server at https://openforallofus.com/api/mcp.

What it does

Reads every entry in the official MCP registry.
Checks each server that runs as a remote Streamable HTTP endpoint: one MCP handshake and one tools/list, nothing else. No tool is ever called.
Reads GitHub signals for linked repositories: stars, last push, licence, archived, missing.
Accepts signed reports: "this server works / is broken / is unsafe", backed by a signed decision record in the open Cedulon format. Signed reports outrank everything measured here.
Publishes the measurements as open data (/data/servers.csv, CC BY 4.0).

Every number on the site is derived from the data files at build time; no page carries a hand-typed count.

Layout

code

scripts/katalog.mjs      read the official MCP registry          -> data/katalog.json
scripts/github.mjs       repository signals (GitHub GraphQL)     -> data/github.json
scripts/probe.mjs        handshake + tools/list per remote server -> data/probe.json
scripts/build-index.mjs  join, flag, derive counts               -> data/index.json, data/facts.json
web/                     Next.js site, MCP endpoint, REST API
tests/                   report verification, claim guard, count consistency

data/ is not in git; rebuild it with the scripts.

Run it

npm install && npm --prefix web install
npm run catalog                                   # ~6 min
node scripts/github.mjs                           # needs a logged-in GitHub CLI
UV_THREADPOOL_SIZE=64 node scripts/probe.mjs --fresh && UV_THREADPOOL_SIZE=64 node scripts/probe.mjs --retry
node scripts/build-index.mjs
npm test
npm run dev                                       # http://localhost:3000

UV_THREADPOOL_SIZE matters: Node resolves DNS on a four-thread pool by default, and thousands of dead domains starve it until live servers start timing out.

The check, and how to opt out

The probe sends agora-probe/0.1 (+https://openforallofus.com/probe), holds at most one connection per host, and gives each server 12 seconds. To stop the check against your endpoint or correct your page, open an issue or write to the address on /method.
