FAQ
Questions
How do I install Entity Enricher?
Copy the http config for Cursor, Claude Desktop, Claude Code, or VS Code on this page. It uses the publisher's install, not a PlugMCP proxy.
Does Entity Enricher need an API key?
No required environment variable is listed on this record.
What transport does Entity Enricher use?
Entity Enricher is reached over HTTP.
When was Entity Enricher last checked?
Last checked 2026-10-18. Multi-LLM entity enrichment: schemas, single/batch enrichment, fusion, model benchmarks.
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 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/
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
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.
In the Entity Enricher web UI: Settings → API Keys → New
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.
For Claude Desktop, edit ~/Library/Application Support/Claude/claude_desktop_config.json
(macOS) or %APPDATA%\Claude\claude_desktop_config.json (Windows):
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.
Guides and tool descriptions
Server instructions explain the workflows. Tool descriptions explain individual calls,
including preconditions, costs and consequential effects. Detailed modeling, recovery and
migration guidance is loaded only when needed.
Use MCP resources/list to discover the guide index (enricher://docs) and each guide,
then resources/read on the desired URI. Guides do not run a model. Clients decide how
resources enter model context; reading them is not guaranteed to be token-free.
The following public recipes are generated from the same packaged Markdown the server
serves. Edit the source guides in the main repository, not these generated copies.
If a client cannot read MCP resources, use these public links. The guides complement
individual tool contracts; ordinary calls do not require reading them all.
Tools
58 tools, spanning the full schema-authoring and enrichment surface:
Category
Tool
Description
Discovery
list_models
List available model keys, nominal capabilities, languages, strategies, auto-selected defaults and organization profile_limits.
Schemas
generate_sample
Generate editable sample JSON from a free-text request for schema authoring.
Schemas
list_schemas
List saved schemas in your organization, pinned first.
Schemas
get_schema
Read a saved schema with its properties, annotations and input_contract.
Schemas
create_schema_from_sample
Generate and auto-save a schema from reviewed samples, returning schema_id, schema content and record links.
Schemas
save_schema
Save a directly authored schema and return its ID and link.
Schemas
update_schema
Edit a saved schema's metadata or replace its full schema_content without an LLM call.
Schemas
get_schema_part
Read only the schema fragment needed for an edit.
Schemas
get_enum_candidates
List observed values outside each open enum's current vocabulary, with counts from recent enrichment records.
Schemas
update_schema_property
Edit or remove one property by path without replacing the full schema.
Schemas
add_schema_property
Add a property under the root (parent_path=''), an object path or '$defs.X'.
Schemas
move_schema_property
Move one property into the root, an object path or '$defs.X', preserving its flags and expertise.
Schemas
resolve_unify_proposal
Resolve one pending entity-type unification proposal from get_schema.
Schemas
nest_schema_region
Materialize an entity region from get_schema's x-entityMap.
Schemas
Tool signatures are the callable contract. The wrappers share backend services, but do not
expose every REST/UI option. Schema mutations require editor; benchmark mutations/runs
require owner plus a benchmark-enabled plan. Database registration/credentials require
owner plus a sync-enabled plan. See each tool for its requirements.
Data resources
Resource template
Meaning
enricher://schemas/{schema_id}
Schema working copy as Markdown. For a linked published contract use get_schema(version="published").
enricher://records/{record_id}
Output and metrics as Markdown; get_record adds expertise and database-delivery diagnostics.
Jobs and errors
Long-running work uses this server's start → poll → fetch interface. Start tools return a
job_id; generate_sample can already be paused or completed when it returns. Poll
get_job_status, answer paused questions through answer_job_question, and retrieve records
by list_records(job_id=...). A missing in-memory job is not proof of completion; check for
persisted records. Cancellation does not undo earlier records or database writes.
Most failures return success: false, error_code and message; some older tools return
only error or message. A successful MCP transport response does not imply successful
work. Inspect classification warnings, failed model legs, and partial/rejected database
outcomes even when an output is present. Detailed recovery is in the enrichment guide.
Scope and limitations
The MCP single/batch enrichment tools do not expose web-search activation; sample generation does.
Batch enrichment has no fixed 100-entity cap, but live quotas/credits can stop remaining work.
The batch tool has no database_sync=false option; the single-entity tool does.
Record deletion/restoration, detailed cost analytics, benchmark result import/export and some database administration remain in the web app or REST API.
Schema documents use the supported JSON Schema dialect with Entity Enricher annotations; see the schema reference before authoring one directly.
This public repository contains documentation and client examples. The server is embedded in
the Entity Enricher backend and maintained in the private monorepo; this directory is synced
