Apideck MCP Server

Model Context Protocol server for the Apideck Unified API. Connect any MCP-compatible agent to 200+ connectors — accounting systems, HRIS platforms, CRM, file storage, and more — through one integration.

Claude Desktop (.mcpb plugin bundle)

Apideck ships a Claude plugin bundle (.mcpb — Anthropic's Model Context Protocol Bundle format). Drop it into Claude Desktop and you get the full server (330 endpoint tools + 4 workflow tools) with API key / consumer ID / app ID prompted via the standard plugin UI.

pnpm mcpb:build       # → dist/mcp-server.mcpb (~590 KB)

The bundle is built locally; CI publication to GitHub Releases is deferred. Open the .mcpb with Claude Desktop's plugin installer; Claude Desktop reads manifest.json to wire credentials and spawn the server.

Tools

330 tools across 10 unified APIs:

Workflow tools

Intent-grouped workflows orchestrate multiple calls behind a single MCP tool — saving agents the round-trips and field-plumbing they routinely get wrong.

Hosted

The server is live at:

https://mcp.apideck.dev/mcp

Pass credentials via headers:

Consumer scoping (optional)

The consumer ID is optional at connect time. Leave APIDECK_CONSUMER_ID / x-apideck-consumer-id unset to start the server unscoped, then supply or override the consumer per call by passing a consumer_id argument to any tool:

execute_tool({ name: "crm-contacts-all", input: { consumer_id: "acme-inc" } })

Precedence: the per-call consumer_id argument wins over the APIDECK_CONSUMER_ID env var / x-apideck-consumer-id header.

• Unscoped calls work for application-scoped endpoints that don't need a consumer — e.g. webhook logs (webhook-event-logs-all) and vault-connections-all.
• Consumer-scoped endpoints called without a consumer return Apideck's "consumer required" error, so set consumer_id (or the env/header) for those.

Locking identity (opt-in)

To pin identity to the boot header/env and stop agents from switching consumer or connection per call, start with --lock-identity (CLI) or append ?lock_identity=true (hosted). Locked calls ignore per-call consumer_id / service_id arguments. Off by default. Vault consumer tools that take consumer_id as a path parameter (e.g. vault-consumers-one) only accept the locked consumer; any other value, or no locked consumer, is refused. service_id path parameters (e.g. vault-connections-one) are unaffected.

Three Modes

Dynamic mode

Agents discover tools progressively — ~85% fewer tokens than loading all 330 schemas upfront:

list_tools({})
  → { total: 330, domains: [{ name: "accounting", count: 143 }, ...],
      hint: "Call list_tools(domain=X) or list_tools(search_terms=[...])" }

list_tools({"search_terms": ["invoices"]})
  → accounting-invoices-list, accounting-invoices-create, accounting-invoices-get, ...

describe_tool_input({"name": "accounting-invoices-list"})
  → Full JSON Schema with all parameters

execute_tool({"name": "accounting-invoices-list", "input": {"request": {"limit": 10}}})
  → Invoice data from the connected accounting system

You can combine dynamic mode with a scope filter:

{
  "mcpServers": {
    "apideck": {
      "command": "node",
      "args": ["dist/bin/mcp.js", "--mode", "dynamic", "--scope", "read"],
      "env": { "APIDECK_API_KEY": "...", "APIDECK_CONSUMER_ID": "...", "APIDECK_APP_ID": "..." }
    }
  }
}

Code mode

Code mode exposes two tools instead of 330+. Designed for agents that prefer calling endpoints as methods rather than tool calls:

1. apideck_search — find endpoints by substring, returns camelCase method names
2. apideck_run — execute a JS script with apideck.<methodName> bound to live endpoint dispatchers, sandboxed in node:vm
