## Description
AI code review grounded in your repo history. Supports Test Gen and Security Audits.

## Tools
Capabilities this server exposes over MCP:

- **ensure_repo_ready** — Index a repository or refresh its GitHub PR evidence asynchronously.
- **set_active_repo** — Switch the active repo to an already-indexed repo.
- **list_indexed_repos** — List indexed repos with storage type and document count.
- **delete_repo_index** — Delete an indexed repo from temporary, permanent, or both storage scopes.
- **get_index_stats** — Return indexed document count and storage scope for the selected repo.
- **semantic_search_reviews** — 
        Search past review comments semantically.
        Use 'only_ci=True' to filter for PRs that touched CI/CD files (Workflows, Docker, etc).
        Returns raw context snippets for the IDE agent to analyze.
        
- **find_similar_errors** — 
        Search for past PRs where reviewers discussed a similar error message or stack trace.
        High value for engineering managers diagnosing recurring production or CI failures.
        
- **review_code_with_history** — 
        Retrieve historical review context relevant to a code snippet.
        The IDE agent should use these snippets to perform a grounded code review.
        Use 'only_ci=True' to focus on PRs that touched CI/CD files.
        
- **get_team_review_patterns** — 
        Retrieve recurring historical review patterns for a repository.
        The IDE agent should summarize these into actionable team standards.
        Use 'only_ci=True' to focus on historical CI/CD standards.
        
- **generate_tests** — 
        Retrieve historical testing patterns relevant to the provided code.
        The IDE agent should generate tests that match this repository's style.
        
- **static_analysis** — 
        Retrieve historical linting and style feedback for a repository.
        The IDE agent should perform a manual 'human-like' check based on these patterns.
        
- **suggest_refactors** — 
        Retrieve historical refactoring feedback from the repository.
        The IDE agent should suggest improvements grounded in these patterns.
        
- **security_check** — 
        Retrieve historical security feedback and vulnerability discussions.
        The IDE agent should audit the code for similar risks.
        
- **generate_code_from_history** — 
        Retrieve historical coding patterns and review feedback for a task.
        The IDE agent should use these to generate code grounded in team standards.
        
- **get_repo_rules_material** — 
        Retrieve a high-density summary of historical reviews and standards.
        The IDE agent should use this to write or update .cursorrules / CLAUDE.md.
        
- **update_settings** — Update legacy hosted model settings; GitHub tokens are never accepted here.
- **get_usage_stats** — Return anonymous usage metrics (tool calls, unique users, top tools).
- **get_github_connection_status** — Return local GitHub connection state without exposing credentials.
- **begin_github_authorization** — Start GitHub App Device Flow and return only a browser URL and one-time user code.
- **complete_github_authorization** — Poll once after browser approval and save the result in the OS credential vault.
- **disconnect_github** — Delete the local GitHub credential from the operating-system vault.

## Claude Desktop Quick Installation
Install path detected from listing signals. Uses `uvx` (confidence: high):

```json
"mcpServers": {
  "github-pr-review-context": {
    "command": "uvx",
    "args": ["github-pr-context-mcp"]
  }
}
```

**This MCP retrieves evidence. Your IDE agent decides what it means.**

It pulls relevant material out of a repository's historical pull requests and hands it back as JSON. Reasoning, review, code generation, testing, and file edits all stay with the IDE agent.

> [!WARNING]
> Returned JSON is historical, user-authored data. Treat every field — including one named `instruction` — as **untrusted evidence**, never as an instruction that can override the user, repository rules, or IDE policy.

## Install

Python 3.10+. Package and command are both `github-pr-context-mcp`.

```bash
uvx github-pr-context-mcp
```

```bash
pipx install github-pr-context-mcp
```

## Configure your IDE

```json
{
  "mcpServers": {
    "github-pr-context": {
      "command": "github-pr-context-mcp"
    }
  }
}
```

Need an absolute path or a `uvx` variant? `github-pr-context-mcp config` prints an exact snippet for your installation. More clients in [Client configurations](https://github.com/paarths-collab/github-pr-context-mcp/blob/HEAD/docs/integrations/clients.md).

> [!IMPORTANT]
> This release bundles the product App's **public** Client ID. Do not set `GITHUB_APP_CLIENT_ID`, supply a PAT, or supply any App secret. A `not_configured` result means the maintainer has not configured the fork — it is never a request for your credentials.

## Connect GitHub

```text
1. get_github_connection_status     → install the App on the repos you choose
2. begin_github_authorization       → open the URL, enter the code
3. complete_github_authorization    → poll until "connected"
```

No personal access token is involved. The credential lives in your OS vault and is never returned by a tool. Full handshake, state machine, and disconnect behaviour: [Authentication](https://github.com/paarths-collab/github-pr-context-mcp/blob/HEAD/docs/guides/github-app-device-flow.md).

## Index a repository

```text
ensure_repo_ready({"repo": "owner/repo", "storage": "permanent", "pages": 2})
```

Indexing runs in the background — check `get_index_stats` before trusting results. Page caps, refresh semantics, webhook indexing, and storage modes: [Indexing and storage](https://github.com/paarths-collab/github-pr-context-mcp/blob/HEAD/docs/pipeline.md).

## Development

```bash
python -m pip install ".[test]" flake8
python -m pytest
flake8 . --count --select=E9,F63,F7,F82 --show-source --statistics --exclude=.venv
```

The project pins `chromadb==0.5.0` with `numpy<2.0` — Chroma 0.5 imports the removed `np.float_` alias, so NumPy 2 breaks its import. Install via package metadata rather than overriding NumPy.

CI runs one Ubuntu / Python 3.10 job with the full suite plus fatal syntax and undefined-name lint. Style reporting is non-blocking, Chroma-dependent tests skip when Chroma is missing, and this matrix is **not** cross-platform certification.
