Sign up at app.anchord.ai/signup and create an API key in Settings > API Keys.

What the assistant can call

Once Anchord MCP is connected, these are the calls the assistant has available:

  • resolve_company — Resolve a company to a canonical AnchorID
  • resolve_company_batch — Batch company resolution (max 200)
  • resolve_person — Resolve a person to a canonical AnchorID
  • resolve_person_batch — Batch person resolution (max 200)
  • get_entity — Fetch an AnchorID with optional linked records
  • get_entity_export — Export the golden record for an AnchorID
  • link_source_record — Link a source record to an AnchorID
  • unlink_source_record — Soft-delete a source record link
  • guard_write — Pre-write safety check (evaluation-only)
  • guard_write_batch — Batch pre-write safety check (max 200)
  • ingest_record — Ingest a source record into Anchord

Configuration and credentials

You will need 3 environment variables: ANCHORD_API_KEY, YOUR_ANCHORD_API_KEY, ANCHORD_API_BASE_URL. The server will not start without them, which is usually why the tools fail to appear on a first run. Keep credentials in your client's env block or a secrets manager rather than in a file you might commit.

Setting it up

Being a remote server, there is no local install. You register the endpoint with your client, authorise it once, and the tools appear.

Choosing this one

This sits in the developer tooling group, where several servers overlap in what they claim to do but differ sharply once you actually set them up. Anchord MCP's toolset — resolve_company, resolve_company_batch, resolve_person and 8 more — is a fair guide to whether it matches your workflow. It is maintained by nolenation04; worth a glance at recent repository activity before you build anything load-bearing on it.

This entry was verified against Anchord MCP's own documentation before publication; SyncDev keeps the directory reviewed rather than auto-generated.

Before you rely on it

  • Your data travels to the provider's service, so the usual questions apply about what you send and what they retain.
  • With 11 tools registered it takes up a noticeable share of the context window; turn it off in projects that never touch Anchord MCP.
  • Missing credentials fail quietly in some clients — if no tools show up, check the environment block first.
  • MCP clients confirm each tool call by default. Leave that on until you have watched what the anchord mcp mcp server does with a few real requests.
