Anchorr MCP

What anchorr-mcp MCP server does

The anchorr-mcp MCP server exposes Anchorr CRM operations to MCP-compatible agents. Its tool surface covers contact and company records, deal stages, sequences and templates, activities and tasks, enrichment, and the configuration and status of Anchorr’s autonomous prospecting and reply-qualification agent.

The service is hosted at https://anchorr-mcp.mgthompo.workers.dev/mcp. Agents authenticate with an Anchorr API key in a Bearer authorization header. Keys are issued from Anchorr settings and can be scoped by tool category, allowing separate agents to receive only the CRM permissions they need.

How it works

anchorr-mcp MCP server sends tool calls to Anchorr’s hosted MCP endpoint. Enrichment requests can resolve an individual contact by email or name and domain, resolve a company by domain or name, or process up to 200 contact IDs in one bulk operation. The enrichment flow can try Apollo, Hunter, and AI research providers in sequence. Results share a cache with the Anchorr web application, so a result obtained in one interface may be available in the other.

The server also exposes composite resources for broader context than an individual tool call. Organization overview, deal brief, contact brief, and company brief resources combine related CRM data such as pipeline records, activities, research, sequence enrollments, and tasks. These resources suit prompts that ask an agent to prepare for a meeting or summarize an account.

Every tool call is recorded in Anchorr’s MCP audit log with the API key, parameters, outcome, and duration. Enrichment records include provider attempts and cost in micro-dollars; cached enrichment results do not incur provider cost.

Setup and configuration

Create an API key in Anchorr at anchorr.app/settings, then configure the hosted endpoint in an MCP client. The request must include Authorization: Bearer ancr_live_.... Claude Desktop can use the endpoint and header directly in its MCP server configuration. Cursor uses the same URL with the server type set to streamable-http in ~/.cursor/mcp.json.

No local process or package installation is described in the provided setup. The hosted service is available for use with an Anchorr account, and usage is measured against the account plan’s quotas. Use narrowly scoped keys when an agent only needs enrichment or a limited combination of CRM write categories.

Tools and capabilities

The 25 tools are organized into these areas:

• Enrich contacts and companies, including bulk enrichment for up to 200 contact IDs.
• List, retrieve, create, and update contacts and companies; bulk-create contacts and enroll contacts in sequences.
• Create and manage deals, move them between stages, close them, and work with next-step and stale-deal data.
• Create and update sequences and templates containing email, wait, and task steps with contact and company placeholders.
• List activities, record activities, create tasks, and complete tasks.
• Inspect and update agent configuration, review candidates, and change candidate status.

anchorr-mcp MCP server also provides four URI resources: an organization overview and briefs for deals, contacts, and companies. These resources aggregate related records so an agent can retrieve a business context snapshot without manually chaining several reads.
