MCP Servers - Give AI Agents Access to the Urantia Book

There are two MCP servers available — one for accessing Urantia Book data directly, and one for searching this documentation site.

Server	URL	Capabilities	Purpose
API MCP Server	`api.urantia.dev/mcp`	19 tools, 2 resources, 2 prompts	Search, paragraphs, entities, audio, Bible (WEB) + UB↔Bible cross-references
Docs MCP Server	`urantia.dev/mcp`	1 tool	Search the documentation site

API MCP Server

The Urantia Papers API includes a built-in Model Context Protocol (MCP) server that exposes API endpoints as tools, papers/entities as resources, and study workflows as prompts that any AI agent can use natively.

https://api.urantia.dev/mcp

Listed in the official registries

This server is published in the canonical registries that MCP-aware clients query for discovery:

MCP Registry (Anthropic-stewarded, official) — dev.urantia/urantia-papers. Verifiable: curl "https://registry.modelcontextprotocol.io/v0/servers?search=urantia"
Smithery — community marketplace with one-click install + 100/100 quality score

One-click install via Smithery

The fastest way to add this server to your MCP client is via Smithery — it generates the right config snippet for your client and handles the install.

Manual setup

Add the server to your MCP client config directly. No API key, no installation, no build step.

Claude Desktop
Claude Code
Cursor / Windsurf

Add to ~/Library/Application Support/Claude/claude_desktop_config.json (macOS) or %APPDATA%\Claude\claude_desktop_config.json (Windows):

{
  "mcpServers": {
    "urantia-papers": {
      "url": "https://api.urantia.dev/mcp"
    }
  }
}

Restart Claude Desktop. You’ll see 19 tools available.

Add to .mcp.json in your project root:

{
  "mcpServers": {
    "urantia-papers": {
      "url": "https://api.urantia.dev/mcp"
    }
  }
}

Add to your MCP settings:

{
  "mcpServers": {
    "urantia-papers": {
      "url": "https://api.urantia.dev/mcp"
    }
  }
}

Works with any client that supports MCP Streamable HTTP transport.

Available Tools

The MCP server exposes 19 tools using dot-notation names organized into a navigable namespace tree. All tools advertise read-only annotations and ship with output schemas for structured responses.

Tool	Description
`toc.get`	Get the full table of contents — all 4 parts and 197 papers. Best starting point.
`papers.list`	List all 197 papers with metadata (id, title, partId, labels).
`papers.get`	Get a single paper with all its paragraphs. Supports `include_entities`.
`papers.sections`	Get all sections within a paper, ordered by section number.

Paragraphs

Tool	Description
`paragraphs.get`	Look up a paragraph by reference. Supports 3 formats: `"1:2.0.1"`, `"2:0.1"`, `"2.0.1"`.
`paragraphs.context`	Get a paragraph with N paragraphs before and after (configurable `window`, 1-10).
`paragraphs.random`	Get a random paragraph. Great for exploration.

Search

Tool	Description
`search.fulltext`	Full-text search. Modes: `and` (default), `or`, `phrase`. Filters: `paper_id`, `part_id`.
`search.semantic`	Semantic similarity search via vector embeddings. Finds conceptually related passages.

Entities

Tool	Description
`entities.list`	Browse 4,400+ entities (beings, places, orders, races, religions, concepts). Filter by `type` or search by `q`.
`entities.get`	Get entity details: name, type, aliases, description, related entities, citation count.
`entities.paragraphs`	Get all paragraphs that mention a specific entity.

Audio

Tool	Description
`audio.get`	Get audio file URLs for a paragraph. Accepts any reference format.

Bible (World English Bible)

Tool	Description
`bible.books`	List all 81 books (39 OT + 15 deuterocanonical + 27 NT) with OSIS codes, canon, chapter counts.
`bible.book`	Get a single book’s metadata. Accepts OSIS, USFM, full names, and aliases (case-insensitive).
`bible.chapter`	Get all verses in a chapter, ordered by verse number.
`bible.verse`	Get a single verse by `bookCode`, `chapter`, `verse`.
`bible.verse.urantia_parallels`	Reverse cross-reference — top-10 Urantia paragraphs semantically nearest a Bible verse.
`bible.search.semantic`	Live semantic search over all 38,034 Bible verses; results arrive with their nearest UB paragraphs already attached.

Cross-reference enrichment on existing tools

paragraphs.get, paragraphs.random, search.fulltext, and search.semantic accept two optional booleans that attach pre-computed semantic neighbors to each result:

Param	What you get
`include_bible_parallels`	Top-10 Bible verses semantically nearest each UB paragraph.
`include_urantia_parallels`	Top-10 Urantia paragraphs semantically nearest each UB paragraph (UB ↔ UB “see also”).

Both can be combined. Parallels are pre-computed via text-embedding-3-large cosine similarity, so adding them is cheap. Note: these are semantic neighbors, not curated linguistic parallels (e.g. Faw’s Paramony) — best results trend conceptual rather than verse-citation.

Resources

In addition to tools, the server exposes two resource templates clients can read directly:

URI Template	Description
`urantia://paper/{id}`	A single paper rendered as plaintext markdown with section headings and paragraph references. Useful for full-paper context in RAG or summarization.
`urantia://entity/{id}`	An entity (being, place, order, race, religion, or concept) with description, aliases, related entities, and references to all paragraphs that mention it.

Prompts

The server also publishes two reusable prompt templates for common study workflows:

Prompt	Arguments	Description
`study_assistant`	`topic` (optional)	Primes the model to act as a Urantia Book study guide. Optionally focuses the session on a specific topic or passage.
`comparative_theology`	`topic`, `tradition`	Structures a comparison between a Urantia Book teaching and another religious or philosophical tradition (e.g. Buddhism, Stoicism).

Example Prompts

Once connected, try asking your AI agent:

“Search the Urantia Book for passages about love” — uses search.fulltext
“What does the Urantia Book say about what happens after death?” — uses search.semantic
“Read Paper 1 about the Universal Father” — uses the urantia://paper/1 resource
“Show me paragraph 2:5.10 with surrounding context” — uses paragraphs.context
“Find all entities of type ‘place’” — uses entities.list
“What entities are mentioned in paragraph 0:0.1?” — uses paragraphs.get with include_entities
“Compare what the Urantia Book teaches about the soul with Stoic philosophy” — uses the comparative_theology prompt
“Find Urantia Book paragraphs related to Matthew 5:3” — uses bible.verse.urantia_parallels
“Search the Bible for passages about forgiveness and show the related Urantia teachings” — uses bible.search.semantic
“Show me 0:0.1 with both Bible parallels and related Urantia paragraphs” — uses paragraphs.get with include_bible_parallels and include_urantia_parallels

How It Works

The MCP server uses Streamable HTTP transport, which means:

No local process — it runs on the same Cloudflare Worker as the API
Stateless — each request creates a fresh server instance (no sessions to manage)
Same rate limits as the REST API (100 requests/minute per IP)
Same data — MCP tools query the database directly, returning the same results as the REST endpoints

MCP vs REST

Both give you access to the same data. Choose based on your use case:

	MCP (`api.urantia.dev/mcp`)	REST (`api.urantia.dev/*`)
Best for	AI agents (Claude, Cursor, etc.)	Apps, scripts, manual exploration
Protocol	JSON-RPC over Streamable HTTP	Standard HTTP
Auth	None	None
Surface	19 tools, 2 resources, 2 prompts	All endpoints + `/tools/openai`, `/tools/anthropic` for SDK use
Response format	MCP content blocks	JSON with `data`/`meta` wrappers

Docs MCP Server

Mintlify provides a hosted MCP server that lets AI agents search these documentation pages — useful for discovering endpoints, understanding usage patterns, and learning the API.

Using Both MCP Servers

For the best experience, add both servers to your client:

{
  "mcpServers": {
    "urantia-papers": {
      "url": "https://api.urantia.dev/mcp"
    },
    "urantia-dev-docs": {
      "command": "npx",
      "args": ["-y", "@anthropic-ai/mcp-remote@latest", "https://urantia.dev/mcp"]
    }
  }
}

API MCP Server (api.urantia.dev/mcp) — 19 tools for accessing Urantia Book data, the World English Bible, and UB↔Bible cross-references
Docs MCP Server (urantia.dev/mcp) — 1 tool for searching this documentation site

Building a Custom MCP Server

If you need custom logic (e.g., combining multiple tools, caching, or preprocessing results), you can build your own MCP server that calls our REST API. See the Build an MCP Server tutorial for a step-by-step guide.
