The same command works against a self-hosted\ndeployment or the hosted service. Its only dependencies are `httpx` and `mcp`.\n\n## Install\n\n```bash\npip install 'git+https://github.com/jmluang/postara-mcp.git'\n```\n\nOr run it without installing, using [uv](https://docs.astral.sh/uv/):\n\n```bash\nuvx --from 'git+https://github.com/jmluang/postara-mcp.git' postara-mcp\n```\n\n## Configure\n\nThe server reads two environment variables:\n\n| Variable | Required | Default | Notes |\n|---|---|---|---|\n| `POSTARA_API_KEY` | yes | — | A scoped API key created in the Postara app. |\n| `POSTARA_BASE_URL` | no | `http://127.0.0.1:18080` | URL of the running Postara instance. |\n\nCreate the API key in Postara (Workspace -> API keys). Give it only the scopes\nthe client needs:\n\n- `read` — discover mailboxes, list folders and messages, fetch messages.\n- `mark_seen` — change read/unread state. Add this only if the client should\n  mark messages seen.\n\nOne `postara-mcp` process uses one API key, so it sees exactly the mailboxes\nthat key can access.\n\n## Connect Claude Desktop\n\nAdd the server to `claude_desktop_config.json`:\n\n```json\n{\n  \"mcpServers\": {\n    \"postara\": {\n      \"command\": \"uvx\",\n      \"args\": [\"--from\", \"git+https://github.com/jmluang/postara-mcp.git\", \"postara-mcp\"],\n      \"env\": {\n        \"POSTARA_BASE_URL\": \"http://127.0.0.1:18080\",\n        \"POSTARA_API_KEY\": \"pst_live_your_key_here\"\n      }\n    }\n  }\n}\n```\n\nIf you installed the package with `pip`, set `\"command\": \"postara-mcp\"` and drop\n`args` instead. Restart Claude Desktop; the Postara tools then appear.\n\nCursor and Cline use the same MCP server config shape.\n\n## Tools\n\n| Tool | Purpose |\n|---|---|\n| `list_mailboxes` | Discover mailboxes the key can access. …","publisher":null,"homepage":null,"repository":null,"version":"0.1.0","license":"Apache-2.0","protocols":["mcp"],"tags":["mcp"],"pricing":null,"endpoints":[{"url":"pypi:postara-mcp","type":"package_pypi","auth":null,"probeable":false}],"skills":null,"tools":null,"extra":null,"attribution":{"kind":"pypi","name":"pypi","license":"pypi","summary":"pypi","version":"pypi","description":"pypi"}},"derived":{"capabilities":[{"slug":"dev.package-management","name":"Packages & Dependencies","confidence":0.859,"provenance":"derived"},{"slug":"dev.version-control","name":"Version Control","confidence":0.745,"provenance":"derived"}],"categories":["dev"],"language":"en"},"observed":{"status":"unknown","statusReason":"Distributed as a package to run locally; no network endpoint to check.","lastOkAt":null,"lastProbedAt":null,"statusComputedAt":null,"reliability30d":null,"latestObservations":[],"tools":null,"package":{"name":"postara-mcp","registry":"pypi","observedAt":"2026-11-10T00:24:33.923Z","publishedAt":"2026-05-23T12:22:41.564473Z","latestVersion":"0.1.0"},"toolSurface":null,"endpointFacts":[]},"verification":{"claimed":false,"claimedAt":null,"proofs":[]},"provenance":{"sources":[{"source":"pypi","key":"postara-mcp","url":"https://pypi.org/project/postara-mcp/","firstSeenAt":"2026-09-10T10:23:36.635Z","fetchedAt":"2026-11-10T00:23:02.548Z","normalizedAt":"2026-11-10T00:23:02.548Z"}]},"firstSeenAt":"2026-09-10T10:23:36.635Z","updatedAt":"2026-11-10T00:24:33.923Z"}
