CompanyGraph MCP server

• describe_relationsFree

  Every reference the schemas declare between types, as data read from their tables: the type that declares it, the field or Section.Column it is declared on, the type it names, its form (ref, ref? or qualifier), whether it is a list, whether it is required and how many of it a page may hold (min and max); which type owns which; the values every field or column typed enum permits; the joins a schema declares between its tables, among them the tables whose repeated references carry distinct roles; and the kind of list each list section holds. Every term is explained in the answer. The whole vocabulary and what it constrains in one answer, for a diagram or an audit.

• describe_ruleFree

  One rule as written, by its number.

• describe_schemaFree

  One type's schema as the instance vendors it: file location, frontmatter fields, sections and their columns, purpose and writing rules. Its relations come beside it as data, both ways: the type that owns it, the types it owns, each reference it declares and each reference another schema declares to it, with how many a page may hold, the values each of its enums permits, and the joins and list kinds the schema declares.

• fetchFree

  One entity by the id search returned, with its page as written. A bare name is accepted only when exactly one type holds it.

• find_evidenceFree

  Everything the model says about one skill, every edge into it grouped by the type of the page that drew it: a profile's claim, via Skills.Skill, with its level; each evidence row under that claim, via Evidence.Skill, with what it shows and the experience it came from; each experience that lists the skill; and any other page that references it. Attributes are verbatim.

• get_entityFree

  One entity by type and canonical name: its frontmatter, sections and tables, with every reference it makes and every reference made to it. A name resolves within its type; a name of an owned type, such as an experience or a phase, is unique only within its owner, and one held by two owners is refused with every id named, for fetch.

• list_checksFree

  Every check the checker runs over an instance, from the checker release this server was built with: what each is called, the rule it cites and that rule's title. A list and no verdict, since this server runs none of them; the answer says who does. It shows which rules a script enforces and which are left to a reader.

• list_entitiesFree

  The id, canonical name and tagline of every entity of one type.

• list_rulesFree

  The rules the instance is held to, from the CONVENTIONS.md its core vendors: each rule's number, its title and the part of the file it stands in. A schema cites a rule by number, such as R9, and this is where the number is read.

• list_typesFree

  Every type the instance's schemas declare, with its tagline, its owner type and how many entities it holds.

• searchFree

  Entities whose name, tagline, fields, sections or table cells contain the query, case-insensitive, listed by type then name with the fields that matched. Use fetch with a result's id.
