scvi-tools-mcp 0.1.0

MCP server for scvi-tools - deep probabilistic analysis of single-cell omics data

scvi-tools-mcp

An MCP (Model Context Protocol) server that gives LLMs structured access to scvi-tools knowledge: model documentation, tutorials, API reference, workflow templates, and community FAQ.

No runtime model execution — pure knowledge layer. Works with Claude Desktop, Cursor, and any MCP-compatible client.

---

Quick Start

Claude Desktop

Add to ~/Library/Application Support/Claude/claude_desktop_config.json:

{
  "mcpServers": {
    "scvi-tools": {
      "command": "uvx",
      "args": ["scvi-tools-mcp"]
    }
  }
}

Cursor / other clients

{ "command": "uvx", "args": ["scvi-tools-mcp"] }

Local install

pip install scvi-tools-mcp
scvi-tools-mcp

Tool	Description
recommend_model	Rank models by task and data type — start here
get_model_overview	Full model description, use cases, inputs, outputs
get_model_parameters	Key __init__ and train() parameters with defaults
get_setup_anndata_guide	Exact setup_anndata() call + required obs/var fields
validate_data_requirements	Pass/fail checklist for your AnnData against a model
list_tutorials	Browse tutorials by category

search_tutorials	Keyword search across all tutorials
get_api_reference	Signature + docstring for any public class or function
search_api	Search public symbols by keyword
get_workflow_template	Step-by-step code template for an analysis task

Knowledge Sources

All knowledge is baked into the package as Markdown files at build time. No network calls at tool-call time.

Directory	Content
knowledge/models/	One .md per model — description, use case, parameters
knowledge/tutorials/	60+ tutorials converted from .ipynb (code + prose only)
knowledge/api/	Extracted class signatures and docstrings
knowledge/user_guide/	Narrative documentation from the scvi-tools user guide
knowledge/faq/github_issues.md	Top GitHub issues snapshot
knowledge/faq/discourse_threads.md	Discourse forum thread snapshot

---

Knowledge Refresh (CI)

Three monthly GitHub Actions jobs keep knowledge current — each opens a PR if a diff is found:

Workflow	Schedule	What it does
refresh_knowledge.yaml	1st of month	Re-scrapes GitHub issues + Discourse threads
sync_tutorials.yaml	1st of month	Fetches new .ipynb from scvi-tools, converts to .md
sync_model_knowledge.yaml	1st of month	Checks CHANGELOG, regenerates model docs for changed models

All workflows also support workflow_dispatch for manual runs.

Development

git clone https://github.com/ori-kron-wis/scvi-tools-mcp
cd scvi-tools-mcp
pip install -e ".[dev]"
pytest

Rebuild knowledge manually

# Convert tutorials from a local scvi-tools checkout
python scripts/convert_notebooks.py /path/to/scvi-tools/docs/tutorials/notebooks \
    src/scvi_tools_mcp/knowledge/tutorials

# Extract API docs (requires scvi-tools installed)
pip install -e ".[scvi]"
python scripts/extract_api_docs.py

# Re-scrape external knowledge
python scripts/scrape_external.py

Adding a new model

1. Run scripts/extract_api_docs.py after updating scvi-tools.
2. Add the model name to MODEL_NAMES in src/scvi_tools_mcp/tools/_constants.py.
3. Add requirements to MODEL_REQUIREMENTS in _data_prep.py if needed.
