The LEDGER MCP is the product surface: a Cloud-proxied endpoint at https://api.cloud.blnkfinance.com/mcp/{instance_id} with 33 tools that read and write real ledger data, gated behind a Blnk Cloud plan and mcp:read / mcp:write scopes. The DOCUMENTATION MCP is a Mintlify docs-search server at https://docs.blnkfinance.com/mcp, open with no auth, 3 tools, and it cannot touch a ledger. deployment: below describes the ledger MCP, because that is the agent surface a buyer is asking about. deployment: mode: remote endpoint: https://api.cloud.blnkfinance.com/mcp/{instance_id} auth: oauth verified: searched templated: true template_variables: - name: instance_id description: >- Identifier of the Blnk Core instance to attach to, found in Settings > MCP in the Blnk Cloud dashboard. There is no tenant-neutral URL; every customer gets their own path. note: >- verified: searched, not probed -- the endpoint cannot be exercised anonymously and there is no instance_id to substitute without a Cloud account. api.cloud.blnkfinance.com returns 401 {"error":"Authorization header is required"} on every path, which is consistent with the documented model. Auth is Bearer with either a Cloud API key or an OAuth access token; the OAuth authorization-server metadata IS served anonymously and is captured in well-known/blnkfinance-oauth-authorization-server.json. servers: - id: ledger name: Blnk MCP (Cloud ledger) status: published transport: http endpoint: https://api.cloud.blnkfinance.com/mcp/{instance_id} auth: type: bearer accepts: - Blnk Cloud API key - OAuth 2.0 access token scopes: - name: mcp:read description: Read-only access to ledger data through MCP tools. - name: mcp:write description: Read and write access through MCP tools. availability: >- Requires a Blnk Cloud Sandbox ($100/mo) or Production ($1,000/mo) plan; the pricing table lists MCP as "Not included" on the free open-source tier. architecture: >- All MCP traffic is proxied by Blnk Cloud.
