Companycam

Remote MCP server for the CompanyCam API, built for use as a claude.ai custom connector (and any other MCP client that speaks Streamable HTTP).

• Transport: MCP Streamable HTTP (stateless JSON-RPC over POST) — no SSE stream, no sessions
• Runtime: single zero-dependency Vercel serverless function (api/_lib/mcp-core.ts)
• Auth to CompanyCam: server-side COMPANYCAM_API_TOKEN (Bearer)
• Auth to the endpoint (two equivalent modes, same MCP_SHARED_SECRET):
  • Secret path: https://<deployment>/mcp/<MCP_SHARED_SECRET> — for the claude.ai custom-connector dialog
  • Bearer header: https://<deployment>/mcp with Authorization: Bearer <MCP_SHARED_SECRET> — for Claude Tag "Connect an app" credentials (see .mcp.json, which registers this repo as a Claude Tag plugin pointing at /mcp)

Tools (26)

No delete tools are exposed by design — the shared server-side token means every connector user acts as the token owner, so destructive operations are limited to archiving (reversible).

Area	Tools
Company / users	get_company, get_current_user, list_users
Projects	list_projects, get_project, create_project, update_project, archive_project, restore_project, update_project_notepad
Project people	list_project_assigned_users, assign_user_to_project
Project content	list_project_documents, list_project_comments, add_project_comment
Photos	list_project_photos, list_photos, get_photo, add_photo, update_photo_description
Photo metadata	list_photo_tags, add_photo_tags, list_photo_comments, add_photo_comment
Tags	list_tags, create_tag

Notes:

• add_photo requires the image to already be hosted at a publicly accessible URL — that's how the CompanyCam API works (it downloads from uri).
• Write tools accept acting_user_email to attribute the action to a specific CompanyCam user (X-CompanyCam-User header).
• Photo responses collapse the uris renditions array into a {type: url} map to keep chat context small.

Environment variables (Vercel)

Var	Purpose
COMPANYCAM_API_TOKEN	CompanyCam API access token (CompanyCam → Settings → API)
MCP_SHARED_SECRET	Random string that becomes the secret path segment of the connector URL

Add to claude.ai

Settings → Connectors → Add custom connector:

• Name: CompanyCam
• Remote MCP server URL: https://<production-domain>/mcp/<MCP_SHARED_SECRET>
• Leave OAuth fields empty (auth is the secret URL + server-side token).

Develop

npm install
npm test          # local protocol smoke tests, no network needed
vercel deploy     # preview
vercel deploy --prod

Smoke-test a deployment:

curl -s https://<domain>/mcp/<secret> -X POST -H 'Content-Type: application/json' \
  -d '{"jsonrpc":"2.0","id":1,"method":"tools/list"}'
