mcp-ingest 0.1.1

SDK + CLI to describe, validate, and register MCP servers into MatrixHub

🦾 MCP Ingest

Discover, describe, and register AI agents with ease.

---

mcp-ingest is a tiny SDK + CLI that turns any MCP server/agent/tool into a MatrixHub‑ready artifact. It lets you:

• Discover servers from a folder, Git repo, or ZIP — even whole registries (harvester).
• Describe them offline → emit manifest.json + index.json (SSE normalized).
• Validate in a sandbox or container (handshake, ListTools, one CallTool).
• Publish to S3/GitHub Pages and Register to MatrixHub (/catalog/install).

Built for Python 3.11, packaged for PyPI, with strict lint/type/test gates.

You can catalog millions of MCP candidates offline and install on demand per tenant/workspace — the fastest path to building the Matrix of interoperable agents and tools.

Install

pip install mcp-ingest

For contributors:

python3.11 -m venv .venv
source .venv/bin/activate
pip install -U pip
pip install -e ".[dev,harvester]"

Quickstart

SDK (authors)

from mcp_ingest import describe, autoinstall

# Generate manifest.json and index.json without running your server
paths = describe(
    name="watsonx-mcp",
    url="http://127.0.0.1:6288/sse",
    tools=["chat"],
    resources=[{"uri":"file://server.py","name":"source"}],
    description="Watsonx SSE server",
    version="0.1.0",
)
print(paths)  # {"manifest_path": "./manifest.json", "index_path": "./index.json"}

# Optionally register into MatrixHub (idempotent)
autoinstall(matrixhub_url="http://127.0.0.1:7300")

CLI (operators)

# Detect → describe (offline)
mcp-ingest pack ./examples/watsonx --out dist/

# Register later (POST /catalog/install)
mcp-ingest register \
  --matrixhub http://127.0.0.1:7300 \
  --manifest dist/manifest.json

Harvest a whole repo

Harvest a multi-server repository (e.g., the official MCP servers collection):

mcp-ingest harvest-repo \
  https://github.com/modelcontextprotocol/servers/archive/refs/heads/main.zip \
  --out dist/servers

Outputs one manifest.json per detected server and a repo-level index.json that lists them all. Optionally --publish s3://… and/or --register.

MatrixHub integration

• Preferred path: POST /catalog/install with the inline manifest (what autoinstall() and mcp-ingest register do). And when is installed and running the mcp server can be later imported in MCP Gateway for future use.
• Idempotent by design: HTTP 409 is treated as success; safe to re-run.
• SSE normalization: we auto-fix URLs to end in /sse unless the manifest explicitly requests /messages or a different transport.

Deferred install: You can describe millions of candidates offline, then install only when a tenant wants them.

---

Transports

MCP Ingest supports three server transports when building manifests:

• SSE (default): URL is normalized to /sse if needed.
• STDIO: provide an exec block with cmd (e.g. Node servers via npx).
• WS: WebSocket endpoints are preserved as provided.

Example STDIO snippet:

{
  "mcp_registration": {
    "server": {
      "name": "filesystem",
      "transport": "STDIO",
      "exec": { "cmd": ["npx","-y","@modelcontextprotocol/server-filesystem"] }
    }
  }
}

Development

Use the Makefile helpers:

make help
make setup      # create .venv (Python 3.11)
make install    # install package + dev extras
make format     # black
make lint       # ruff
make typecheck  # mypy
make test       # pytest
make ci         # full gate (ruff+black+mypy+pytest)
make build      # sdist/wheel → dist/

Local harvester API:

uvicorn services.harvester.app:app --reload
# POST /jobs {"mode":"harvest_repo","source":"<git|zip|dir>","options":{}}

---

CI & Quality

• Ruff (lint), Black (format), Mypy (types), Pytest (coverage)
• GitHub Actions workflow in .github/workflows/ci.yml
• Package is built and uploaded as CI artifact; PyPI publishing via Twine is supported.

---

Security & Safety

• Idempotent HTTP and retries with exponential backoff (409 → success).
• Sandboxes (process & container) with timeouts and memory caps.
• No secrets stored at rest; inject via environment only.
• Logs are structured; per-job trace IDs in the harvester path.

---

Roadmap

• More detectors (framework coverage), stronger schema inference.
• Richer validation (multiple tool calls, golden tests), SBOM/provenance by default.
• Global public index shards (CDN) fed by the harvester.
