Entity Enricher MCP server

Entity Enricher MCP Server

A hosted Model Context Protocol server for Entity Enricher, available at https://entityenricher.ai/api/mcp/ (Streamable HTTP).

From an MCP-compatible client you can:

• Design reusable schemas from sample data or documents and edit properties directly.
• Enrich single entities or lists, with multilingual fields and multiple models.
• Fuse results and recover failed expertise domains without repeating successful work.
• Resolve recurring objects to semantic identities and curate their aliases or uncertain matches.
• Derive relational tables and migrations for your PostgreSQL, MySQL or SQLite database.
• Benchmark enrichment, sample generation and schema generation on your own tasks.

Schema validation and model agreement do not establish factual truth or freshness. Inspect the actual sources, failures and partial outcomes. A successful generation, entity-layer admission and application on your external replica are distinct outcomes.

The MCP server needs no local installation. Optional database delivery uses ee-database on your replica host; its DSN stays there. Managed hosts can provision automatically; manual pairing is also supported.

Quickstart

Option 1 — OAuth (recommended)

For claude.ai, Claude Code, Cursor, and any MCP client that implements the standard OAuth flow. No API key to create or paste — the client discovers the authorization server automatically, your browser opens the Entity Enricher consent screen, and the connection acts on your behalf with your own role. Revoke it anytime under Settings → API Keys → Connected Apps.

Claude Code

claude mcp add --transport http entity-enricher https://entityenricher.ai/api/mcp/

Then run /mcp in a session and pick Authenticate — your browser opens the consent page. More options (project .mcp.json, API-key fallback): examples/claude-code/

claude.ai

Settings → Connectors → Add custom connector with URL https://entityenricher.ai/api/mcp/, then click Authorize on the consent screen. Walkthrough: examples/claude-ai-remote.md

Cursor / other OAuth-capable clients

Register the URL with no headers and the client prompts you to sign in: examples/cursor/mcp.json

Option 2 — API key (static JSON configuration)

For clients configured via a JSON file rather than an interactive sign-in (Claude Desktop, Continue, Zed) — and for headless/CI use.

organization access key. Pick a role — operator (read-mostly), editor (create/edit schemas), or owner (full control, required for benchmarks). Copy the ent… value; it's only shown once.

1. In the Entity Enricher web UI: **Settings → API Keys → New

(macOS) or %APPDATA%\Claude\claudedesktopconfig.json (Windows):

1. For Claude Desktop, edit ~/Library/Application Support/Claude/claudedesktopconfig.json

{
     "mcpServers": {
       "entity-enricher": {
         "url": "https://entityenricher.ai/api/mcp/",
         "headers": { "X-API-Key": "ent_your_key_here" }
       }
     }
   }

Restart Claude Desktop. Full file: examples/claude-desktop/

Try it

List my Entity Enricher schemas, then enrich "Sanofi" against the pharmaceutical company

schema in English and French.

The client discovers the tools, reads the selected schema and returns the result with a link. Automatic model selection is available; consequential choices are reviewed when needed.
