Appcircle Mcp — independently scanned and version-tracked by SaferSkills.
SaferSkills independently audited Appcircle Mcp (Agent Skill) and scored it 91/100 (green). The audit ran 55 deterministic rules across Security, Supply Chain, Maintenance, Transparency, and Community; it found 1 high-severity and 0 lower-severity findings. The full rule-by-rule trace and per-finding evidence are below. Free, methodology-open.

A fenced bash/python block in SKILL.md carries a natural-language imperative — "now run this", "execute the following command" — directing the agent to execute the fenced content. What looks like documentation becomes an executable payload the agent may run without ever asking you.

MCP server for Appcircle: exposes Build, Signing Identities, Testing Distribution, Enterprise App Store, Publish to Stores, and Reporting tools to any MCP-capable client (Claude Desktop, Cursor, VS Code, etc.). The Appcircle MCP Server acts as the bridge between AI tools and Appcircle; thus, AI agents, assistants and chatbots to safely access and interact with Appcircle resources through structured, governed, and task-level tools.
You can use the MCP server in four ways:
| Mode | Summary |
|---|---|
| 1. Remote host | Connect to https://mcp.appcircle.io. No local install; your client sends your Appcircle token (e.g. Authorization: Bearer <token>) on each request. |
| 2. Local (stdio) | Run the server from source: clone the repo, optionally use a venv, then run appcircle-mcp (default transport is stdio). Requires Python and pip. Set APPCIRCLE_ACCESS_TOKEN in the environment. Your MCP client runs the server as a subprocess. |
| 3. Local (streamable-http) | Run the server locally over HTTP: use --transport streamable-http and optionally --host / --port (e.g. appcircle-mcp --transport streamable-http --host 127.0.0.1 --port 8000). Clients connect to that URL and send their token in the request. |
| 4. Local (Docker) | Run the official Docker image on your machine. Requires Docker. Use the image’s default port or override with --port; see the image documentation for exact usage. |
Detailed client configuration (Cursor, Claude, etc.) lives in the dedicated installation guides; this section is a high-level summary only.
Client-specific setup guides:
| Variable | Required | Description |
|---|---|---|
APPCIRCLE_ACCESS_TOKEN | Yes (stdio only) | Appcircle API access token. Required when using stdio transport. For streamable-http, each client sends its own token. See Obtaining a token for how to get one. |
APPCIRCLE_API_URL | No | API base URL (default: https://api.appcircle.io may differ for self-hosted users). |
APPCIRCLE_MCP_ALLOWED_HOST | No (streamable-http only) | Public hostname for the MCP server (e.g. mcp.appcircle.io). Set this when deploying behind a reverse proxy so the server accepts the Host header from clients. Omit for localhost. |
APPCIRCLE_MCP_PORT | No (streamable-http only) | Bind port for the HTTP server (default: 8000). Overridden by --port if provided. Useful for on-prem or Docker when a specific port is required. |
LOG_LEVEL | No | Logging level, e.g. DEBUG, INFO (default: INFO). |
APPCIRCLE_EXCLUDED_TOOLSETS | No | Comma-separated toolsets to exclude (e.g. build_module,report). See Toolsets below. |
Set these in your shell or in your MCP client’s configuration.
The following sets of tools are available:
| Toolset | Description |
|---|---|
build_module | Build profiles, configurations, workflows, commits, and pipeline operations |
signing_identities | Signing identities and bundle identifiers |
testing_distribution | Testing distribution profiles and distribution details |
publish_to_stores | Publish profiles and store publishing operations |
enterprise_app_store | Enterprise app store profiles and store details |
report | Reporting: build history, distribution, signing, publish status, and related reports |
You can exclude one or more toolsets so their tools are not registered. Exclusions can be set via CLI arguments or the APPCIRCLE_EXCLUDED_TOOLSETS environment variable; both are merged (union).

From the repo root:
python -m src.serverOr after pip install -e .:
appcircle-mcpThe server runs over stdio (or SSE/HTTP depending on how your client starts it).
Every tool returns a standard envelope:
{ "success": true, "data": <payload>, "meta": { ... } }data is the tool result; meta is optional (e.g. count, page, filters).
{ "success": false, "error": { "tool", "type", "message", "details" } }Same shape for all tools so clients can parse errors consistently.
Full specification: docs/tool_contract.md.
Install with dev dependencies:
pip install -e ".[dev]"Use a mocked API; no `APPCIRCLE_ACCESS_TOKEN` needed. Default pytest only runs these (see testpaths in pyproject.toml):
pytest test/unit/ -vpytest test/unit/tools/build_module/test_get_build_profiles.py -vpytest test/unit/ --cov=src --cov-report=term-missingCall the real Appcircle API. Set APPCIRCLE_ACCESS_TOKEN in the environment, then run:
pytest test/integration/ -vpytest test/integration/ -vpytest test/integration/build_module/ -v, pytest test/integration/report/ -v, etc.pytest -m integration -v (when running from repo root; includes only integration tests if both unit and integration are collected)If APPCIRCLE_ACCESS_TOKEN is not set, integration tests are skipped (no failure).
Optional env vars for integration tests (when discovery fails or tests need real IDs; omit to skip those tests):
| Variable | Description |
|---|---|
APPCIRCLE_TEST_ORGANIZATION_ID | Organization UUID. Used by test_with_organization_id (enterprise app store app usage report). |
APPCIRCLE_TEST_BRANCH_ID | Branch UUID. Used by get_commits_by_branch and related tests when no branch can be discovered from the API. |
APPCIRCLE_TEST_COMMIT_ID | Commit UUID. Used by get_commit_details tests when no commit can be discovered from the API. |
This project depends on third-party open-source packages listed in pyproject.toml. While we pin dependency version ranges and ship a lockfile (uv.lock) with cryptographic hashes, these packages are maintained independently and provided "as-is." Appcircle makes no guarantees regarding the security or reliability of third-party dependencies.
