Overview

biblical-atlas-mcp exposes the biblical-atlas Bible atlas through ten read-only MCP tools. It searches Spanish names and Bible references, retrieves sourced records, filters events and people by time or attributes, traces connections, and finds nearby places. The server downloads the atlas data, caches it locally, and checks for refreshed data hourly. Use it for Spanish-language biblical research involving chronology, geography, people, events, and source-linked passages.

Use cases

  • Search Spanish biblical names and Bible books
  • Trace relationships between biblical figures
  • Explore events by year, person, place, or passage
  • Find atlas locations near a place or coordinate
  • Check who was active or ruling in a historical year

Key features

  • Spanish and English Bible book search
  • Source-linked record retrieval
  • Year, event, role, and place filtering
  • Relationship-chain discovery
  • Radius searches for atlas places
  • Hourly cached dataset refresh

How Biblical Atlas MCP works

What biblical-atlas-mcp does

biblical-atlas-mcp makes the biblical-atlas Bible atlas available to AI agents through MCP. Its dataset covers people, places, events, periods, letters, journeys, books, passages, offices, and related records. Responses preserve the atlas’s Spanish names and summaries.

Results include atlas identifiers and, where available, links to the corresponding record card on the atlas website. Source links accompany the returned information: list responses identify an available source and the total source count, while get_record returns the complete source list.

All ten tools are read-only. They return both structured MCP content and JSON text, and do not modify the atlas data.

How it works

The package fetches the atlas’s public data file rather than bundling a database or a copy of the atlas data. It caches that file locally and performs an hourly conditional refresh, allowing repeated requests to use the cached dataset when it remains current.

The server supports MCP over stdio and streamable HTTP, and handles MCP revisions from 2024-11-05 through 2026-07-28. It also supports clients using the older initialize flow alongside newer discovery and stateless request behavior.

Dates use signed years in both directions. For example, -607 represents 607 a.e.c. Bible references can be supplied in Spanish or English forms where supported, such as Hch 16:1 and Acts 16:1.

Setup and configuration

Node.js 18 or newer is required. Running the npm package downloads a release binary for the host platform on first use and verifies it against checksums published with the package.

A stdio configuration can be added with the command npx -y biblical-atlas-mcp. Claude Code can register it with claude mcp add biblical-atlas -- npx -y biblical-atlas-mcp. Claude Desktop, Cursor, VS Code, and Codex configurations are also documented using their respective MCP configuration formats.

Tools and capabilities

  • search finds records by name or Bible book, accepts Spanish and English book names, ignores accents and case, and can return a suggestion for an unsuccessful match.
  • get_record returns one record with detailed relationships, family information, offices, coordinates, candidate sites, events at a place, and all available sources.
  • get_records retrieves up to 20 records in one request.
  • list_records lists periods, letters, journeys, finds, tours, books, months, places by kind, or people holding an office.
  • list_events filters events by year or range, person, place, role, kind, or Bible book, with date or story ordering.
  • people_in_year identifies people alive, ruling, or active in a year and includes supporting evidence.
  • lookup_passage finds atlas content associated with a Bible reference, including relevant events, people, places, and records.
  • find_connection calculates the shortest chain of family, succession, and companionship ties between two people.
  • places_near searches for places within a radius of another place or a coordinate.
  • dataset_info reports dataset freshness, record counts, and accepted kind and role filter values.

Limitations and notes

The atlas is Spanish-language, so names and summaries are returned in Spanish. The tools only read the atlas’s own data file; they do not write, delete, or access other data sources. Because the package obtains its data remotely instead of including it, the initial run requires access to the atlas’s public data endpoint.
