Biomed Agent

Biomedical Agent Workspace

Connecting AI to biomedical data.

biomed-agent is an MCP-backed biomedical research workspace for Claude Code, Codex, and other coding agents. It provides server registration, diagnostics, and source-backed routing guidance across OpenTargets, Monarch, MyGene, MyChem, and MyDisease.

What It Provides

• MCP server registry and local path handling.
• A tiny diagnostics CLI for server/tool inspection.
• The cross-server research contract for agents.
• Example MCP registration in [mcp.json](mcp.json).

MCP Servers

The default setup expects sibling repos:

• ../opentargets-mcp
• ../monarch-mcp
• ../mygene-mcp
• ../mychem-mcp
• ../mydisease-mcp

Override paths with OPENTARGETS_MCP_PATH, MONARCH_MCP_PATH, MYGENE_MCP_PATH, MYCHEM_MCP_PATH, or MYDISEASE_MCP_PATH.

Setup

uv sync

Install From Git

uvx --from git+https://github.com/nickzren/biomed-agent biomed-agent doctor

doctor needs the MCP repos at the expected sibling paths or matching *_MCP_PATH environment variables.

Install Agent Skill

Copy this into a new Codex or Claude Code session:

Set up biomed-research, the source-backed biomedical research skill for agents.

If npm is available:
npx skills add nickzren/biomed-agent --skill biomed-research -y -g

Otherwise:
dir="${XDG_DATA_HOME:-$HOME/.local/share}/agent-skills"
repo="$dir/biomed-agent"
mkdir -p "$dir"
test -d "$repo" || gh repo clone nickzren/biomed-agent "$repo"
"$repo/install.sh"

Manual install from this checkout:

./install.sh

Diagnostics

uv run biomed-agent list-servers
uv run biomed-agent list-servers --json
uv run biomed-agent list-tools
uv run biomed-agent list-tools --json
uv run biomed-agent list-tools --server opentargets
uv run biomed-agent call-tool opentargets.search_entities '{"query_string":"BRAF","entity_names":["target"]}'
uv run biomed-agent doctor
uv run biomed-agent doctor --json

Init Config

init is print-only. It does not edit Codex, Claude Code, or Cursor settings.

uv run biomed-agent init --runtime codex --print
uv run biomed-agent init --runtime claude --print
uv run biomed-agent init --runtime cursor --print
uv run biomed-agent init --runtime codex --print --mcp-base ../

Tests

uv run pytest tests/ -q

Safety

Research and educational use only. This is not a clinical decision system and must not provide diagnosis, prescribing, dosing, or patient-specific treatment advice.
