Filemark developer docs
Read the client and engagement records in your firm's Filemark workspace and run Filemark's Canadian T2 corporate tax computations from your own systems, over REST or the Model Context Protocol (MCP). The API is read-only: nothing writes to a workspace.
- REST base URL:
https://api.filemark.ca/api/v1 - MCP server:
https://api.filemark.ca/mcp - Contract: the OpenAPI schema, also browsable as the interactive REST reference
- Format: JSON over HTTPS, OAuth 2.0 bearer tokens
- Markdown: any page plus
.md, the whole guide at /llms-full.txt, and an index at /llms.txt
Start here
- Quickstart: mint a token, run a computation, list your clients.
- Definitions: clients, entities, engagements, saved data, targets and cells.
- Authentication for a server integration, or delegated access to connect an AI assistant or other MCP host as a signed-in user.
