GetBible MCP

test PyPI License: GPL v2+

Project and API documentation: getBible.net · MCP usage guide: getBible.net/mcp.

Read-only Model Context Protocol access to all nine GetBible API contracts over both standard MCP transports:

  • Streamable HTTP at the official endpoint https://mcp.getbible.net/, or another host's MCP URL
  • stdio for developers who install the package and let an AI client launch it locally

Both transports expose exactly the same tools, resources, prompts, validation, and scripture-cache integrity rules. Scripture tools default to upstream v3; select api_version: "v2" explicitly for upstream v2. Dictionary, commentary and bookmark operations use v1.

Connect to the official endpoint

GetBible's official MCP endpoint is https://mcp.getbible.net/. Add that exact URL to your AI application's remote MCP connections and select Streamable HTTP. The domain root is the protocol endpoint; do not append /mcp or an API version. The MCP usage page explains how to connect and use the service.

One connection provides Bible retrieval, reference lookup, full-text search, dictionaries, commentaries and public bookmarks across all supported API versions. Your client can discover tools, read the complete API contracts and use the integration-planning prompt. All operations are read-only; select upstream versions through tool arguments.

Public access is free and needs no account or token. It uses the same default anonymous traffic limits as GetBible search. Excess traffic receives HTTP 429; honor Retry-After and reduce your request rate. To request a token for MCP or another GetBible endpoint, contact the GetBible administrators. See the access policy for limits and client guide for connection and token instructions.

You can also connect to a privately operated instance using the URL supplied by its operator. The Python library supports configurable endpoint URLs and local stdio clients.

For ChatGPT and Codex, the plugin package includes GetBible branding and the official connection configuration. The publishing handoff contains listing text, client tests and the steps for the person submitting it. The package is prepared for review; this repository does not claim that the public directory listing is already approved.

For definitions and study material, follow the dictionary and commentary guide. It explains module discovery, entry identifiers, related entries, introductions and verse ranges.

API coverage

Service Versions Capabilities Upstream contracts
api v2, v3 Translation, book and chapter data; catalogs; checksums; v2 text indexes v2, v3
query v2, v3 Resolve individual, ranged and grouped scripture references v2, v3
search v2, v3 Full-text search, filters, ranking, pagination and reference lookup; GET and read-only POST v2, v3
dictionaries v1 Catalogs, metadata, word indexes, definitions, Strong's entries and checksums v1
commentaries v1 Catalogs, metadata, book/chapter commentary, introductions and checksums v1
bookmarks v1 Public topics, verse associations, localized names and checksums v1

The package includes the complete upstream OpenAPI documents. Agents can discover services, inspect an operation's exact parameters and response schemas, then execute that operation. This covers the whole API surface without requiring a separate MCP tool for every HTTP route. Native upstream JSON is preserved, including v3 verse tokens, spans, paragraph markers and additional fields.

What the two transports mean

Transport Who runs the server? How a client connects Best use
Streamable HTTP GetBible or another service operator https://mcp.getbible.net/ or the operator's MCP URL Remote MCP clients
stdio The developer installs this package locally Client launches getbible-mcp --transport stdio Desktop tools, private environments, local process control

stdio does not create a public endpoint. The MCP host starts the command as a child process and exchanges JSON-RPC messages over standard input and output. That local process still reads scripture from the public GetBible API.

Streamable HTTP connects to a remote MCP service using the same package and tool contract. The host chooses its endpoint path, including / or a named path such as /mcp. Use the supplied URL exactly; upstream API versions remain tool arguments.

Public API access and translation rights

Public access requires no account or token by default. Traffic limits, HTTP errors and upstream availability still apply; an integration must handle them instead of assuming every request succeeds. Administrators issue tokens for approved access to individual endpoints.

Use the translation catalog for copyright and rich translation metadata; query/search and chapter results carry compact metadata. Preserve and honor each translation's rights, and each study module's provenance and license. This repository's GPL license applies to the MCP software and does not relicense upstream content.

Correct API use is conditioned on honoring the hash-validation cycle described below. An integration that keeps cached scripture without revalidating its hashes is not complying with the GetBible API usage agreement.

MCP capabilities

Tools

Tool Purpose
list_translations Discover translations, copyright information, metadata, scope, and catalog hashes.
list_books Discover numbered and localized book names and hashes.
list_chapters Discover chapters and chapter hashes.
get_scripture Retrieve a complete translation, book, or chapter with a consistency-checked hash.
query_verses Resolve selected/grouped verses, retaining native version-specific data.
search_verses Search scripture with the upstream filters and pagination.
search_dictionary_entries Find a bounded page of dictionary entry IDs by key, alias or index search text; fetch definitions through the documented entry operation.
get_hash Read one translation, book, or chapter .sha value.
get_hash_manifest Read bulk checksum data for scheduled cache sweeps.
check_for_updates Compare stored hashes and receive exact invalidation actions.
discover_apis Discover services, supported versions and authoritative contracts.
describe_api_operation List operations or inspect exact inputs, outputs and documented errors.
call_api_operation Execute any operation in the supported contracts, including text, checksums and read-only search POST.

All tools are read-only, non-destructive, and idempotent. Scripture tools default to api_version: "v3"; use "v2" explicitly for v2 data. Generic operation tools require a service and version, because operation IDs and parameter names differ across contracts. HTTP POST search is a read operation and does not change server data.

For check_for_updates, specify api_version in each watched item so one batch can safely check several versions.

Mandatory scripture-cache integrity

The MCP server keeps no upstream result cache and recommends using query and search results directly. A downstream application choosing to cache an eligible response must:

  1. Include service, API version and all request inputs in the cache key; retain source HTTP freshness.
  2. Never retain data beyond 30 days (2,592,000 seconds); honor shorter HTTP freshness, Age, Expires, no-cache and no-store. An unchanged hash does not grant an indefinite lifetime.
  3. Invalidate the changed scope and every cached descendant.
  4. Validate the published checksum where available and fetch replacements into temporary storage.
  5. Atomically replace the stale record.

get_scripture checks the matching .sha value before and after retrieving JSON. If a build changes mid-request, it retries once instead of returning mismatched data and hash. Scripture .sha files contain SHA-1 values; dictionary, commentary and bookmark manifests use SHA-256. Query results have no chapter-hash envelope. Search query.sha describes the source translation, not the result payload. Query/search TTL comes from HTTP headers, not a promised JSON field.

See site/v2/cache-policy.md.

Quick local stdio setup

Clone the repository and build an isolated environment:

git clone https://github.com/getbible/mcp.git getbible-mcp
cd getbible-mcp
python3 -m venv .venv
.venv/bin/python -m pip install --upgrade pip
.venv/bin/python -m pip install -r requirements.txt
.venv/bin/python -m pip install --no-deps .

Configure the MCP client with the absolute executable path:

{
  "mcpServers": {
    "getbible": {
      "command": "/absolute/path/getbible-mcp/.venv/bin/getbible-mcp",
      "args": ["--transport", "stdio"]
    }
  }
}

Do not wrap or embed Python inside a shell configuration. The client launches the installed Python entry point directly.

See docs/CLIENTS.md for stdio, remote, and Inspector examples.

Python, JavaScript and PHP applications can connect to the same MCP endpoint using a compatible client. This project ships one Python server package; npm/Composer server packages are not required. Ordinary applications can also call the existing REST endpoints directly. The MCP endpoint uses versioned JSON-RPC discovery and tool requests. The documentation under site/v2/ describes MCP package 2.x and covers every supported upstream API version.

Python library interface

getbible_mcp.create_app(settings=None, api_client=None, *, path="/mcp") returns a standalone ASGI application. getbible_mcp.create_runtime(..., streamable_http_path="/mcp") returns the application, MCP server, client and settings for consumers needing the individual components. Importing the package does not create a default client or server.

The factory default is /mcp; the host can select / or another supported exact path. Clients use the complete endpoint URL published by that host, without appending an API version or assuming a suffix.

The embedding application owns the ASGI lifespan. If mounting the returned application in a parent, the parent must enter the child's app.router.lifespan_context(app) so MCP startup and HTTP client cleanup run correctly. See architecture for package boundaries and configuration for settings. API infrastructure setup is outside this package.

Downloadable packages, TestPyPI, and PyPI

Every successful test workflow run builds and smoke-tests one wheel and one source distribution. GitHub keeps them for 30 days in the run's Artifacts section under the name python-package-distributions. This includes runs started manually from Actions → test → Run workflow, so a package can be downloaded and tested without publishing anything.

The separate publish-testpypi workflow is manually triggered and publishes validated artifacts to TestPyPI. Production publishing runs only after a pull request is merged into main. GitHub must confirm that the triggering commit is that PR's final merge commit before the workflow validates and publishes the package and creates its GitHub tag/release. Open pull requests, direct pushes and manual dispatch cannot publish to production. Retry an incomplete release by rerunning its original post-merge workflow; matching existing PyPI files are not uploaded again.

TestPyPI uses Trusted Publishing. Production PyPI reads the project or account token only from the PYPI_MCP_TOKEN GitHub Actions secret in the protected pypi environment. See docs/PUBLISHING.md for the download, TestPyPI, secret setup, and production release procedures.

sync-openapi checks all nine upstream contracts daily and on demand. Changed contracts receive a coordinated patch-version bump and full validation before the workflow creates or updates one pull request. Review and merge that PR to release the update automatically. Unchanged contracts do nothing. The generic tools gain newly described API operations and schemas from the contracts; unsupported semantics fail validation and require a reviewed implementation change. The workflow does not auto-merge or rewrite curated convenience tools.

Development

python3 -m venv .venv
.venv/bin/python -m pip install -r requirements-dev.txt
.venv/bin/python -m pip install --no-deps -e .
chmod +x scripts/check
./scripts/check

The suite covers all bundled contracts, request validation and serialization, version-preserving responses, HTTP freshness, hash-consistent reads, MCP schema discovery, both transports, static documents, CLI behavior and release packaging. Tests use local fixtures and mock HTTP transports.

To test the official service explicitly, run .venv/bin/python scripts/check_endpoint.py. Add --upstreams to perform representative read-only requests across all nine API contracts, and --expect-version 2.1.1 when checking this release after deployment. The probe bounds requests, response sizes and timeouts; it never runs automatically in CI. A successful health response alone does not establish that API lookups work. See client testing.

Documentation

Versioning

Package release 2.0.2 uses the stable official Python MCP SDK 2.2.0 and a host-selected HTTP endpoint. Package versions and upstream API versions are independent. Scripture tools default to v3; v2 remains fully available through explicit version selection. Never mix upstream v2 and v3 payloads under one cache key.

The nine packaged contracts and static snapshots are reviewed release inputs. Use .venv/bin/python scripts/refresh_contracts.py --check to check upstream drift, or --write to refresh the packaged and static copies together. Run the full checks before committing an API contract update. Do not handwrite reduced OpenAPI substitutes. The nine files under site/contracts/ are the complete static API catalog.
