BioMCP: Biomedical Model Context Protocol

BioMCP is an open source (MIT License) toolkit that empowers AI assistants and agents with specialized biomedical knowledge. Built following the Model Context Protocol (MCP), it connects AI systems to authoritative biomedical data sources, enabling them to answer questions about clinical trials, scientific literature, and genomic variants with precision and depth.

MCP Review Certification

BioMCP is certified by MCP Review. This certification ensures that BioMCP follows best practices for Model Context Protocol implementation and provides reliable biomedical data access.

Why BioMCP?

While Large Language Models have broad general knowledge, they often lack specialized domain-specific information or access to up-to-date resources. BioMCP bridges this gap for biomedicine by:

Providing structured access to clinical trials, biomedical literature, and genomic variants
Enabling natural language queries to specialized databases without requiring knowledge of their specific syntax
Supporting biomedical research workflows through a consistent interface
Functioning as an MCP server for AI assistants and agents

Biomedical Data Sources

BioMCP integrates with multiple biomedical data sources:

Literature Sources

PubTator3/PubMed - Peer-reviewed biomedical literature with entity annotations
bioRxiv/medRxiv - Preprint servers for biology and health sciences
Europe PMC - Open science platform including preprints

Clinical & Genomic Sources

ClinicalTrials.gov - Clinical trial registry and results database
MyVariant.info - Consolidated genetic variant annotation
TCGA/GDC - The Cancer Genome Atlas for cancer variant data
1000 Genomes - Population frequency data via Ensembl
cBioPortal - Cancer genomics portal with mutation occurrence data

Available MCP Tools

BioMCP provides 13 specialized tools for biomedical research:

Core Tools (3)

1. Think Tool (ALWAYS USE FIRST!)

CRITICAL: The think tool MUST be your first step for ANY biomedical research task.

# Start analysis with sequential thinking
think(
    thought="Breaking down the query about BRAF mutations in melanoma...",
    thoughtNumber=1,
    totalThoughts=3,
    nextThoughtNeeded=True
)

The sequential thinking tool helps:

Break down complex biomedical problems systematically
Plan multi-step research approaches
Track reasoning progress
Ensure comprehensive analysis

2. Search Tool

The search tool supports two modes:

Unified Query Language (Recommended)

Use the query parameter with structured field syntax for powerful cross-domain searches:

# Simple natural language
search(query="BRAF melanoma")

# Field-specific search
search(query="gene:BRAF AND trials.condition:melanoma")

# Complex queries
search(query="gene:BRAF AND variants.significance:pathogenic AND articles.date:>2023")

# Get searchable fields schema
search(get_schema=True)

# Explain how a query is parsed
search(query="gene:BRAF", explain_query=True)

Supported Fields:

Cross-domain: gene:, variant:, disease:
Trials: trials.condition:, trials.phase:, trials.status:, trials.intervention:
Articles: articles.author:, articles.journal:, articles.date:
Variants: variants.significance:, variants.rsid:, variants.frequency:

Domain-Based Search

Use the domain parameter with specific filters:

# Search articles (includes automatic cBioPortal integration)
search(domain="article", genes=["BRAF"], diseases=["melanoma"])

# Search with mutation-specific cBioPortal data
search(domain="article", genes=["BRAF"], keywords=["V600E"])
search(domain="article", genes=["SRSF2"], keywords=["F57*"])  # Wildcard patterns

# Search trials
search(domain="trial", conditions=["lung cancer"], phase="3")

# Search variants
search(domain="variant", gene="TP53", significance="pathogenic")

Note: When searching articles with a gene parameter, cBioPortal data is automatically included:

Gene-level summaries show mutation frequency across cancer studies
Mutation-specific searches (e.g., "V600E") show study-level occurrence data
Cancer types are dynamically resolved from cBioPortal API

3. Fetch Tool

Retrieve full details for a single article, trial, or variant:

# Fetch article details
fetch(domain="article", id="34567890")

# Fetch trial with all sections
fetch(domain="trial", id="NCT04280705", detail="all")

# Fetch variant details
fetch(domain="variant", id="rs113488022")

Domain-specific options:

Articles: detail="full" retrieves full text if available
Trials: detail can be "protocol", "locations", "outcomes", "references", or "all"
Variants: Always returns full details

Individual Tools (10)

For users who prefer direct access to specific functionality, BioMCP also provides 10 individual tools:

Article Tools (2)

article_searcher: Search PubMed/PubTator3 and preprints
article_getter: Fetch detailed article information

Trial Tools (5)

trial_searcher: Search ClinicalTrials.gov
trial_getter: Fetch all trial details
trial_protocol_getter: Fetch protocol information only
trial_references_getter: Fetch trial publications
trial_outcomes_getter: Fetch outcome measures and results
trial_locations_getter: Fetch site locations and contacts

Variant Tools (2)

variant_searcher: Search MyVariant.info database
variant_getter: Fetch comprehensive variant details

Note: All individual tools that search by gene automatically include cBioPortal summaries when the include_cbioportal parameter is True (default).

Quick Start

For Claude Desktop Users

```
{
  "mcpServers": {
    "biomcp": {
      "command": "uv",
      "args": ["run", "--with", "biomcp-python", "biomcp", "run"]
