MCP Server - Coda.io

A Model Context Protocol (MCP) server implementation for seamless integration with Coda’s API, providing various tools for document, table, and data management.

Features

• Table Operations
  • Fetch all tables from a document
  • Retrieve specific table data
  • Get table columns information
• Row Management
  • Fetch rows from tables
  • Upsert (insert/update) rows
  • Delete rows
• Column Operations
  • Fetch specific column details
  • Get column metadata

Prerequisites

• Node.js (v20 or higher)
• A Coda API key
• TypeScript knowledge (for development)

Environment Setup

1. Clone or fork this repository in Replit
2. Create a .env file in the root directory:

   PORT=8000
   CODA_API_KEY=your_coda_api_key_here
   

3. Replace your_coda_api_key_here with your actual Coda API key

Installation

The project uses npm for dependency management. To install dependencies:

npm install

Building the Project

Compile TypeScript files to JavaScript:

npx tsc

Running the Server

After building, start the server:

node dist/index.js

Or use the combined command:

npm install && npx tsc && node dist/index.js

The server will start on port 8000 by default, with the following endpoints available:

• GET /sse - SSE connection endpoint
• POST /messages - Message handling endpoint

2. fetch-coda-tables

   • Fetches all tables from a specified document
   • Required parameter: docId

3. fetch-coda-table

   • Fetches a specific table from a document
   • Required parameters: docId, tableId

4. fetch-coda-table-columns

   • Retrieves columns information for a specific table
   • Required parameters: docId, tableId

5. fetch-coda-rows

Error Handling

The server implements comprehensive error handling:

• Environment variable validation
• API response validation
• Request parameter validation
• Proper error messages and logging

Development

The project is structured as follows:

src/
├── tools/           # Individual tool implementations
│   ├── fetch-coda-docs.tool.ts
│   ├── fetch-coda-tables.tool.ts
│   └── ...
└── index.ts        # Main server implementation

Built With

• Express.js - Web framework
• @modelcontextprotocol/sdk - MCP implementation
• Zod - Runtime type checking
• dotenv - Environment configuration

Known Limitations and Future Improvements

The current implementation of tools requires several improvements:

• Enhanced JSON response handling and formatting
