What can you do with this server?

The Apideck MCP server provides a dynamic gateway to 330+ API tools across 10 unified APIs, connecting to 200+ third-party services (Accounting, CRM, HRIS, File Storage, ATS, Issue Tracking, Ecommerce, Webhooks, Vault, Proxy) through a single integration. Core meta-tools: * list_tools – Browse all 330+ tools or filter by search terms/scopes for token-efficient discovery. * describe_tool_input – Retrieve the full JSON Schema for any tool to understand required/optional parameters. * execute_tool – Run any endpoint tool (e.g., list invoices, create CRM contacts, upload files, fetch employees, manage webhooks). * list_scopes – View scope categories (read, write, destructive) for filtering tools by operation type. Additional capabilities: * Workflow tools – Orchestrate multi-step tasks (e.g., month-end close checks). * Binary content handling – Images and audio from File Storage returned as native MCP content blocks. * Multiple modes – Operate in dynamic (progressive discovery), static (all tools exposed), or code (programmatic via apideck_search/apideck_run) modes. * Automatic retries – Built-in request retry logic for improved reliability.

Apideck MCP Server

npm version MCP Registry Glama score License: MIT

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.

Quick Connect

Install in Cursor Install in VS Code

Recommended — prebuilt bundle:

Drag and drop the prebuilt mcp-server.mcpb onto Claude Desktop. Claude reads manifest.json to prompt for credentials and spawn the server — no manual config needed.

NOTE

Learn more aboutDesktop Extensions.

Local stdio (npx) alternative:

Edit ~/Library/Application Support/Claude/claude_desktop_config.json (macOS) or %APPDATA%\Claude\claude_desktop_config.json (Windows):

{
  "mcpServers": {
    "apideck": {
      "command": "npx",
      "args": ["-y", "@apideck/mcp", "start"],
      "env": {
        "APIDECK_API_KEY": "YOUR_API_KEY",
        "APIDECK_CONSUMER_ID": "YOUR_CONSUMER_ID",
        "APIDECK_APP_ID": "YOUR_APP_ID"
      }
    }
  }
}

Restart Claude Desktop after saving. Pin a specific version by replacing @apideck/mcp with @apideck/mcp@0.1.15.

Set credentials in your shell:

export APIDECK_API_KEY="..."
export APIDECK_CONSUMER_ID="..."
export APIDECK_APP_ID="..."

Hosted (recommended):

claude mcp add --transport http apideck https://mcp.apideck.dev/mcp \
  --header "Authorization: Bearer $APIDECK_API_KEY" \
  --header "x-apideck-consumer-id: $APIDECK_CONSUMER_ID" \
  --header "x-apideck-app-id: $APIDECK_APP_ID"

Local stdio (npx):

claude mcp add apideck \
  -e APIDECK_API_KEY="$APIDECK_API_KEY" \
  -e APIDECK_CONSUMER_ID="$APIDECK_CONSUMER_ID" \
  -e APIDECK_APP_ID="$APIDECK_APP_ID" \
  -- npx -y @apideck/mcp start

The start command reads credentials from environment variables only — it does not accept --api-key / --consumer-id / --app-id flags.

        "x-apideck-app-id": "YOUR_APP_ID"
      }

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:

API	Tools	Coverage
Accounting	143	Invoices, bills, payments, suppliers, customers, journal entries, ledger accounts, purchase orders, tax rates, P&L, balance sheet, and more
CRM	50	Companies, contacts, leads, opportunities, pipelines, notes, activities, users
File Storage	32	Files, folders, drives, shared links, upload sessions
HRIS	25	Employees, companies, departments, payrolls, time-off requests
Vault	23	Connections, consumers, sessions, custom mappings, logs
ATS	15	Applicants, applications, jobs
Issue Tracking	15	Collections, tickets, users, tags, comments
Connector	8	APIs, connectors, resources, coverage metadata
Ecommerce	7	Customers, orders, products, stores
Webhook	6	Webhook subscriptions, logs
Proxy	6	GET, POST, PUT, PATCH, DELETE, OPTIONS

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.

Tool	What it does	Calls
`apideck-month-end-close-check`	Fans out aged-creditors, aged-debtors, balance-sheet, and P&L in parallel. Returns a partial result when some reports aren't supported by the connector.	4

Hosted

The server is live at:

https://mcp.apideck.dev/mcp

Pass credentials via headers:

Header	Description
`x-apideck-api-key`	Your Apideck API key
`x-apideck-consumer-id`	The end-user / customer ID in your app
`x-apideck-app-id`	Your Apideck application ID

Three Modes

Mode	Tools exposed	Initial tokens	Best for
`dynamic` (default)	4 meta-tools	~1,300	General-purpose agents, token-sensitive contexts
`static`	All 330 tools	~35–55K	Focused agents doing a specific API
`code`	`apideck_search` + `apideck_run`	~600	Agents that call endpoints programmatically via JS

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:

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

apideck_search("invoices")
  → {
      count: 4,
      endpoints: [
        { name: "accounting-invoices-list",   method: "accountingInvoicesList" },
        { name: "accounting-invoices-create",  method: "accountingInvoicesCreate" },
        { name: "accounting-invoices-get",     method: "accountingInvoicesGet" },
        { name: "accounting-invoices-delete",  method: "accountingInvoicesDelete" }
      ]
    }

apideck_run({
  script: "return await apideck.accountingInvoicesList({ request: { limit: 5 } })"
})
  → Invoice data from the connected accounting system

The sandbox strips process, require, fs, child_process, and other Node globals — scripts only have access to the apideck object.

Scopes

Filter tools by HTTP method class:

Scope	HTTP methods	Flag
`read`	GET, HEAD	`--scope read`
`write`	POST, PUT, PATCH	`--scope write`
`destructive`	DELETE	`--scope destructive`

Reliability

The runtime automatically retries failed requests so transient errors don't surface to your agent:

Retried status codes: 408, 500, 502, 503, 504
Retried network errors: ECONNRESET, ECONNREFUSED, ETIMEDOUT, and similar
Strategy: exponential backoff, up to 4 attempts, capped at 30 s
Idempotency: retries only fire on GET, HEAD, PUT, DELETE, OPTIONS, TRACE — POST/PATCH are not retried automatically

Binary Content

File Storage endpoints that return images or audio send them as native MCP content blocks rather than base64 strings in JSON:

{ "type": "image", "data": "<base64>", "mimeType": "image/png" }
{ "type": "audio", "data": "<base64>", "mimeType": "audio/mpeg" }

Agents that support multi-modal MCP content (Claude, GPT-4o) receive the raw bytes — no extra decoding step needed.
