MCP server for the Populi API v2. It lets Claude, Codex, Cursor and any other Model Context Protocol client look up people, admissions, academics and billing data in your Populi instance, and, if you opt in, make changes.
Package: @kisasa/populi-mcp on npm. Command: populi-mcp. Transports: stdio (local, the default) or Streamable HTTP with sign-in (--http, for Claude and ChatGPT connectors). Protocol: MCP 2026-07-28, plus the 2025-era initialize handshake for older clients, on both transports.
Populi's API has 697 routes across 180 models. Exposing each as its own tool would flood a model's context, so this server gives the model a small toolset plus the API reference itself:
| Tool | What it does |
|---|---|
populi_search_api | Keyword search over the bundled route catalog (applications, invoice, enrollments, ...). |
populi_describe_api | Full reference for one route: path ids, required and optional fields with types, expand options, filter conditions, required Populi roles, docs link. |
populi_get | GET any route. Supports filter, expand, page, limit, and all_pages to merge every page into one list. |
populi_download | GET a route and save the response to a file instead of returning it. For PDF/XLS/CSV exports, transcripts, Data Slicer results, file and backup downloads, and for keeping a large export out of the conversation. |
populi_find_people | Look up people by exact email and/or name. |
populi_status | Shows the instance, key type (sandbox or live), whether writes are on, the files folder and the timeout. verify: true makes one live request to check the key. |
populi_write | POST / PUT / DELETE any route, including multipart file uploads. Only exists when POPULI_ALLOW_WRITES=true. |
Together they cover the whole API: all 492 documented GET routes, all 205 write routes, file uploads and file downloads. Routes that aren't in the bundled catalog work too, since the tools take any path.
A typical exchange: the model searches for the route, reads its parameters, then calls populi_get with a server-side filter.
The catalog is generated from the public API docs and ships inside the package, so searching and describing work offline and cost no API requests.
| Variable | Required | Description |
|---|---|---|
POPULI_BASE_URL | yes | Your instance, e.g. https://yourschool.populiweb.com. A trailing /api2 is fine and optional. Must be https. |
POPULI_API_KEY | yes | An API key token. In Populi: Account & Settings > API > Keys (Account Administrator). Sent as a bearer token to POPULI_BASE_URL only. |
POPULI_ALLOW_WRITES | no | Set to true to enable populi_write. Default: read-only. |
POPULI_FILES_DIR | no | The one folder downloads are saved to and uploads are read from. Default: ~/populi-mcp-files. |
POPULI_TIMEOUT_MS | no | How long one Populi request may take, 1000 to 600000. Default: 120000 (two minutes). Each call can also pass timeout_ms. |
The key's Populi roles decide what it can see. A route the key cannot reach returns a 403 naming the problem; populi_describe_api lists the roles each route needs.
Populi issues separate sk_sandbox_... keys that only work against sandbox instances (live keys only work on live). Point this server at a sandbox while you evaluate it.
With no POPULI_ALLOW_WRITES, the write tool is not registered at all, so the model cannot even attempt a change. When you enable it, populi_write is marked destructive, so clients that prompt for approval will ask before each call. DELETE in Populi is permanent.
Requires Node.js 20 or newer. Every client below runs npx -y @kisasa/populi-mcp, so there is
