TaskBounty Check MCP Server

taskbounty-check

A local check for GitHub Actions and CI maintenance hygiene (third-party action pinning, workflow token permissions, and update automation), built for apps shipped with Lovable, Bolt, Replit, Cursor, or v0.

Local by default. No uploads. No telemetry. It reads only your workflow files, on your machine. The default code path makes no outbound network requests, writes its report locally, and sends nothing anywhere. There is no analytics or phone-home of any kind. Only the opt-in --gh-org mode uses the network (through your own gh session).

Works with Cursor, Claude Code, and Codex (local MCP server, below).

Three ways to use it

1. GitHub Action — add a maintenance check to CI that writes a summary to the run (no PR comments, no source upload):

permissions:
  contents: read
steps:
  - uses: actions/checkout@v4
  - run: npx [email protected] . --github-summary --no-network

Want a human to interpret or fix what the Action surfaces? Request a free launch-safety review. TaskBounty gets no access to your repo, source, or workflows unless you submit that form.

2. Agent / MCP — a local stdio server for Cursor, Claude Code, and Codex:

npx -y [email protected] mcp

3. One-off CLI — scan the current repo locally and write a report:

npx -y [email protected] .

Pin a version (@0.1.6) in committed config and CI for reproducibility. @latest is convenient for a quick one-off, but a pinned version is the reproducible choice.

The GitHub job summary

The Action writes a counts-only maintenance summary to the workflow run (categories and next steps, no filenames, line numbers, or repo source). Below is that exact summary, rendered from this repo's own CI output:

• Methodology — exactly what it reviews and how findings are labeled.
• Privacy and scope — local-by-default data handling.
• Limitations — what it does NOT check (below).

Supported checks (and honest limitations)

Checks (GitHub Actions + CI maintenance hygiene):

• Third-party actions pinned to a movable tag/branch instead of a commit SHA
• Broad (write-all) workflow token permissions
• Missing explicit permissions: block
• Update automation (Dependabot/Renovate) presence
• Context-dependent workflow patterns flagged for private review (e.g. pull_request_target, script injection)

Does NOT check (these need a manual review): exposed secrets, auth/authorization, payments, webhooks, runtime behavior. It is a maintenance/hygiene check, not a full security audit or a penetration test.

What it does

• Reads only your GitHub Actions workflow files and update-automation config, scans them in-process with a deterministic ruleset (the same rules as the public checker), and writes a local HTML + JSON report. It does not execute workflows, install dependencies, or run any repository code.

Modes

Mode	Command	Network
Single repo	npx taskbounty-check .	none
Directory of repos	npx taskbounty-check ./all-repos	none
Explicit paths	npx taskbounty-check --manifest repos.json	none
GitHub org (your gh session)	npx taskbounty-check --gh-org <org>	yes, opt-in

--gh-org uses your existing gh CLI session to fetch each repo's workflow files to this machine (read-only). Your GitHub token is never read by this tool and never sent to TaskBounty.

What is read, written, transmitted

Run --explain-data to print this at any time.

• Reads (allowlist — nothing else is opened): <repo>/.github/workflows/*.yml|*.yaml and update-automation config (dependabot.yml/renovate.json*). Never source files, .env, secrets, SSH keys, credential stores, or anything outside the selected repository roots. Symlinks that escape a root are skipped, never followed.
• Writes (local only): <out>.json (full detail) and <out>.html.
• Transmits: nothing by default. --share uploads nothing — it writes a sanitized, counts-only file (scan id, label, candidate counts by category, private-review count, scanner version, timestamps; repo names only with --include-repo-names) for you to submit manually. Network stays off under --share. Only --gh-org intentionally uses the network.

Flags

--share · --gh-org <org> · --manifest <file> · --org-label <label> · --include-repo-names · --dry-run · --explain-data · --delete-local-report · --no-network (default everywhere except --gh-org) · --out <basename> · --version · --help

TaskBounty receives nothing unless you submit that form. The scan runs locally and the full report stays on your machine; the review form gives us no access to your repositories, source, workflows, or secrets.

GitHub Code Scanning (SARIF)

Emit SARIF 2.1.0 and surface findings in your repo's Security → Code scanning tab:

npx taskbounty-check@latest . --format sarif --output taskbounty.sarif

The SARIF carries deterministic rule ids (taskbounty/<rule>), severity levels, and file/line references — no source contents, secrets, or environment values, and no network access. Confirmed findings are emitted as kind: fail; lower-confidence items as kind: review.

Help interpreting SARIF results: https://www.task-bounty.com/ai-app-security-check/review?utm_source=github&utm_medium=sarif_docs&utm_campaign=workflow_security

Upload it with the official action (full example in examples/code-scanning.yml):

permissions:
  contents: read
  security-events: write
steps:
  - uses: actions/checkout@v4
  - run: npx [email protected] . --format sarif --output taskbounty.sarif
  - uses: github/codeql-action/upload-sarif@v3
    with:
      sarif_file: taskbounty.sarif

Local agent (MCP)

Run a local stdio MCP server so Codex, Claude Code, or Cursor can scan and reason about findings in your editor. It runs locally, makes zero outbound network requests, uploads no source, and never modifies files — generate_fix_plan returns a plan as text for you to apply yourself.

npx taskbounty-check@latest mcp

Tools: scan_repo (local scan summary), explain_finding (plain-language explanation), generate_fix_plan (text fix plan).

Want a human to review the plan? https://www.task-bounty.com/ai-app-security-check/review?utm_source=mcp&utm_medium=mcp_docs&utm_campaign=workflow_security

Cursor — .cursor/mcp.json:

{ "mcpServers": { "taskbounty-check": { "command": "npx", "args": ["-y", "taskbounty-check@latest", "mcp"] } } }

Claude Code:

claude mcp add taskbounty-check -- npx -y taskbounty-check@latest mcp

Codex — in ~/.codex/config.toml:

[mcp_servers.taskbounty-check]
command = "npx"
args = ["-y", "taskbounty-check@latest", "mcp"]

Security

Zero runtime dependencies. Published to npm with provenance (verify on the package's npm page). The default run makes no outbound requests and uploads nothing; see the methodology for the full data-handling and scope boundaries.
