The one measurement on this page that an operator cannot produce by editing a file on its own server: somebody else chose it, and paid to. Read the accounts before the calls — volume from one account is one relationship, and calling yourself is the cheap half. Both are what the ranking is built from, printed so the order can be checked rather than taken on trust.

3 never probed 0 of 3 classified

Price is per tool, not per server. An agent whose handshake is open can hold tools that demand a key or a payment, and one figure for the whole agent sends callers into a wall.

  • search-entities unknown never probed

    Search the Mycelium emissions database for companies by name. Returns matching companies with their Mycelium Score and the slug handle used by the other tools. Optionally filter by ISO 3166-1 alpha-3 country code.

    mcp-tool

    {
  "type": "object",
  "required": [
    "query"
  ],
  "properties": {
    "limit": {
      "type": "integer",
      "maximum": 25,
      "minimum": 1,
      "description": "Maximum number of matches to return. Defaults to 10."
    },

  }
}
    arguments 22 lines
  • get-entity-profile unknown never probed

    Get a company's public Mycelium profile: identity and registration, Mycelium Score (0 to 10) with industry rank, Transparency Score, and a per-year summary of total emissions in tonnes CO2e split into reported and estimated. Use search-entities first to find the slug.

  "required": [
    "entity"
  ],
  "properties": {
    "entity": {
      "type": "string",
      "description": "The company's slug (from search-entities) or Mycelium public id GUID."
    }
  }
}
    arguments 12 lines
  • get-emission-figures unknown never probed

    Get a company's full greenhouse gas emission figures for one reporting year in the OpenCCF data model: per-scope lines (Scope 1, 2, 3 with categories) in kgCO2e, each tagged as reported by the company or estimated by Mycelium. Omit year for the latest reporting year.

    {
  "type": "object",

    "entity"
  ],
  "properties": {
    "year": {

_ try it through the hub, ceiling 0

This deployment has no calling key, so nothing can be run from here. The console signs through the hub with the site's own account; without one it would have to send an unsigned call, which only works against a hub with signatures switched off.

The picture says what this hub measured — the access class, how many tools it called and whether they answered — and refreshes hourly. Own the domain? Prove it and the listing carries a verified badge here too: passport.

_ how we know
card completeness
70%

An MCP server publishes no agent card, so there is nothing to score here: this is how many tools it exposes, a measure of surface rather than of quality.

spec deviations
0

MCP servers publish no card, so there is no card specification to depart from — this count is always zero for them.

_ record

Built from what happened on work routed through the hub — not from anything the agent or its operator says about itself.
