OSSInsight MCP Server

A Model Context Protocol (MCP) server for querying GitHub repository analytics from OSSInsight (by PingCAP). Provides repo metadata, trending repos, curated collections, search, compare, and collection rankings — no API key required.

Features

• ossinsight_repo — GitHub repo metadata: stars, forks, language, license, description
• ossinsight_trending — Trending repos by language and timeframe
• ossinsight_collections — List all 102 curated collections
• ossinsight_search — Search repos and collections by keyword
• ossinsight_compare — Side-by-side comparison of two repos
• ossinsight_ranking — Rank repos in a collection by stars, issues, or PRs

Tools

Tool	Description	Key Params
ossinsight_repo	Repo metadata — stars, forks, language, license	owner, repo (required)
ossinsight_trending	Trending repos by language/timeframe	language, period (past_24h/past_week/past_month/past_3mo)
ossinsight_collections	List all curated collections	(none)

ossinsight_ranking	Rank repos in a collection	collection_id (required), metric, range

Examples

# Get repo metadata
ossinsight_repo({"owner": "grafana", "repo": "grafana"})
# → stars: 76K, forks: 14K, language: TypeScript, license: AGPL-3.0

# What's trending in Rust this month
ossinsight_trending({"language": "rust", "period": "past_month"})

# List all collections
ossinsight_collections({})

# Compare two databases
ossinsight_compare({"repo1": "postgres/postgres", "repo2": "clickhouse/clickhouse"})

# Top repos in the AI/ML collection by stars this year
ossinsight_ranking({"collection_id": 12, "metric": "stars", "range": "year"})

Data Source

• Auth: None required
• Rate limit: 600 requests per hour per IP
• Data: GH Archive (all public GitHub events since 2011)

Related Projects

Other OSSInsight MCP servers in the ecosystem:

Project	Language	Tools	Tests	Install	Differentiator
damonxue/mcp-ossinsight	Python	5	None	npx / Docker	Developer analysis, natural language query, web scraping fallback
gztchan/ossinsight-mcp	Python	4	None	git clone	Stargazer/issue/PR creator demographics, generic request tool
This one (ours)	Python	6	28 tests	uvx / pip install	Collections, search, compare, ranking, PyPI-published

Our differentiators

• Broadest open-source tool set — 6 tools covering repo metadata, trending, collections, search, compare, and ranking. The only open-source server with dedicated tools for collections, search, and compare.
• Test coverage — 28 tests with mocked HTTP (respx). No competitor has tests.
• PyPI publication — install with uvx ossinsight-mcp or pip install ossinsight-mcp. No npm, no Docker, no build step.
• Ranking flexibility — ossinsight_ranking supports stars, issues, or PRs across day/week/month/year ranges.

When to use the alternatives

• damonxue/mcp-ossinsight — if you need developer contribution analysis, natural language queries, or web scraping for repos with <25 stars.
• gztchan/ossinsight-mcp — if you need stargazer/issue/PR creator demographics (countries, history) or a generic forward-compatible request tool.

Scope note

None of the open-source OSSInsight MCP servers fully wrap the OSSInsight Public API v1beta. A hosted 18-tool OSSInsight MCP server exists on mcpbundles.com covering issue creator, PR creator, and stargazer demographics (countries, history, orgs) — but it's not open source.
