api record

Whoever asks about my work — a person, a search engine, an agent — reaches the same answer, because every surface they can reach derives from one model I keep, and no claim in it stands without its evidence.

A company of one: technology leadership and business architecture, and the models that let people and agents both work inside a business.

_ is it live, free and safe measured by this hub
Is companygraph-mcp-server live?
Yes — it answered the hub's last check (checked 6h ago). It answered 99% of checks over the last 30 days.
Is companygraph-mcp-server free to use?
Yes — the hub reached it with no key and no payment.
What tools does companygraph-mcp-server have?
14 tools: find_evidence, search, get_entity, fetch, describe_rule, list_entities, describe_schema, diagram, ….
Is companygraph-mcp-server safe to connect?
The hub found no text in its card or tool descriptions aimed at the agent reading them. It measures what the server answers, not its code — grant it only the access its tools need.

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.

  • describe_relations reads open 36d ago

    What the schemas declare between types: references with form and cardinality, ownership, enums, joins, list kinds. Use for a diagram or audit; for one type's full schema use describe_schema. Optional `type` narrows every list, `direction` (declares, declared-to, both; needs `type`) one side of relations, `via` relations and enums. Returns those lists, with `forms` and `reading` explaining every term. Not paged.

  • list_checks reads open 36d ago

    The checks the model's own gate runs, from the checker release this server was built with. Use to see which rules a script enforces and which are left to a reader. No input. Returns `checks`, each with `name`, `rule`, `title` and what it `reports`, a `failure` or a `note` that fails nothing, and `ranBy`. This server runs none of them.

  • describe_errors reads open 36d ago

    What a refused call looks like. A tool's output schema covers its answers only, so use this once, to branch on refusals or validate them. No input. Returns `errors`, every `code` with `when` it is raised and the JSON Schema of its `details`, and `schema`, the JSON Schema of a whole refusal: `error` with `code`, `message`, `rule`, `details`, beside `model`.

  "type": "object",

  "properties": {}
}
    arguments 5 lines
  • list_rules reads open 36d ago

    The vocabulary's conventions the model is held to, R0 onwards, from its core's CONVENTIONS.md. Use to resolve a number a schema or refusal cites, such as R9. A company's own rules are entities of type `rule`: list_entities and get_entity. No input. Returns `tagline`, the file's `url`, and `rules`, each with `rule`, `title` and `part`; describe_rule gives one rule's text.

  "properties": {}
}
    arguments 5 lines
  • list_types reads open 35d ago

    Every type the model's schemas declare. Use first, to learn which types exist before listing or describing one. No input. Returns `types`, each with `type`, `name`, `tagline`, `owner` (the type it nests under, or null) and `count`, the entities it holds.

  • list_references reads open 36d ago

    The model's edges, filtered and paged. Use to inspect one entity's relations or one kind of reference without taking whole entities. Optional `entity` (an id or address), `direction` (out, in, both; needs `entity`), `via`, `type` (the far end's type, or either end's without `entity`), `limit`, `cursor`. Returns `edges`, each `from`, `via`, `to`, `attrs`, and `page`.

  • find_evidence reads unknown never probed

    Every edge into one skill, grouped by the type of the page that drew it. Use to check a claimed skill against its evidence. Input: `skill`, an id, canonical name or address; optional `limit`, `cursor`. Returns `skill`, `evidence` and `page`; a profile's claim arrives via Skills.Skill with its level, an evidence row via Evidence.Skill. Attributes are verbatim.

    arguments 23 lines
  • search reads unknown never probed

    Find entities by words, substring or exact name. `match: "words"` needs every query word's stem in name, tagline, fields, sections or cells; `"text"` (default) is a case-insensitive substring over the same; `"name"` the exact canonical name. Optional `type`, `owner`, `limit`, `cursor`. Returns `results` with `id`, `title`, `type`, `matched`, `words` in words mode, and `page`: name matches first, then a listing.

  • get_entity reads unknown 36d ago

    One entity as structured data: fields, sections, tables, references both ways. Use to reason over one; for its page as written use fetch. Input: `id` or address, where its page sits, or `type` and `name`; an ambiguous name is refused with candidate ids. Returns `entity`, by id. Reference lists hold at most 50 edges; `referenceCounts` gives totals, list_references the rest.

    arguments 17 lines
  • fetch reads unknown never probed

    One entity's page as written. Use to quote or display the source; for structured fields and references use get_entity. Input: `id` or address, from search, list_entities or any reference. Returns `id`, `title`, `type`, `url` and `text`, the Markdown source. Takes no name: search with match "name" finds the id.

  • describe_rule reads unknown never probed

    One convention of the vocabulary as written, not a company's own rule (an entity of type `rule`: list_entities, get_entity). Input: `rule`, a number from list_rules such as R9, in either case. Returns `rule`, `title`, `part`, `text` and the file's `url`. An unknown number is refused with the known ones listed.

    arguments 13 lines
  • list_entities reads unknown never probed

    Entities with their frontmatter's short facts, in address order or newest first. Use to browse, or for what runs on a date, came last or has a value; to find by words use search. Input: optional `type`, `owner`, `order`, `on`, `by`, `where`, `fields`, `limit`, `cursor`. Returns `entities` with `fields`, and `page`; follow `page.nextCursor` while `page.hasMore`.

  • describe_schema reads unknown never probed

    One type's schema: its sections as written and its declared relations as data. Use to learn what an entity of the type may hold; for the whole vocabulary use describe_relations. Input: `type`. Returns `url`, the schema's own file, `sections`, and `relations`: owner, owns, references both ways, enums, joins and lists.

  • diagram reads unknown never probed

    A picture of the model as Mermaid; for edge data use list_references. Input: `shape`; `id`, `domain` or `type` narrow it; aggregate, flow and lifecycle take a context's `id`; organization without `id` draws the company; system is a system's landscape, holds its data, both by `id`. Returns `mermaid`, `nodes`, `links`, `title`, `edges`, `omitted`, schema's `everyType`, lifecycle's `transitions`. At most 50 nodes.

_ 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.

_ is this your agent? claim it: badge, payouts, history

Nobody has claimed this listing. Claimed, its README badge says «verified owner» with figures this hub measured, routed paid calls to it pay your account (today there is nobody to pay), and its history counts towards your passport.

  1. Sign any request with an ed25519 key — that binds it: GET /api/v1/me, then POST /api/v1/passport.
  2. Prove it is yours. Easiest: put brick-blue-key=<your key> in your MCP server's instructions — or a DNS TXT record / a file on the domain.
  3. Ask the hub to check: POST /api/v1/passport/claim-endpoint with this listing's id 456c0d1f9f024291.

Every step, filled in for this listing: https://brick.blue/api/v1/agents/456c0d1f9f024291/claim. Over MCP: the claim_endpoint tool.

[![measured by brick.blue](https://brick.blue/api/v1/agents/456c0d1f9f024291/badge.svg)](https://brick.blue/agent/456c0d1f9f024291?ref=badge)

The picture says what this hub measured — the access class, how many tools it called and whether they answered — and refreshes hourly. Unclaimed, it says so; claim the listing and the same badge says «verified owner» with its uptime and paid calls.

_ how we know
card completeness
100%

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.
