List of Tools

Nodit MCP Server provides tools enabling AI agents to dynamically discover, understand, and interact with Nodit's Web3 APIs and data infrastructure. The tools minimize token consumption and maintain a lightweight context by modularizing API interactions into distinct steps:

• Tools for Listing API Categories

Retrieve a list of high-level API categories available.

• list_nodit_api_categories

• Tools for Listing API Operations

Fetch available operations within a selected category (Node APIs, Data APIs, Aptos Indexer APIs, Webhook APIs).

• list_nodit_node_apis
• list_nodit_data_apis
• list_nodit_aptos_indexer_api_query_root
• list_nodit_webhook_apis

• Tools for Getting API Specification

Obtain detailed information for a specific API operation (parameters, request/response schema).

• get_nodit_api_spec
• get_nodit_aptos_indexer_api_spec

• Tools for Calling API

Execute an API call using the operationId and validated parameters.

• call_nodit_api
• call_nodit_aptos_indexer_api

Nodit MCP Server communicates using the standard JSON-RPC over stdio protocol, following the Model Context Protocol (MCP) conventions. Currently, only stdio-based communication is supported for server-client interactions.

Running Local Nodit MCP Server

Using npx (Recommended)

npx @noditlabs/nodit-mcp-server@latest

Using local build

# Clone the repository
git clone --recurse-submodules https://github.com/noditlabs/nodit-mcp-server.git

# Move into the project directory
cd nodit-mcp-server

# Install dependencies
npm install

# Build the project
npm run build

Before starting, set your Nodit API key:

export NODIT_API_KEY=your-api-key

Then start the server:

node build/index.js

Communicating with the Local Server

Once the Nodit MCP Server is running locally, you can communicate with it using JSON-RPC over stdio. Here’s how you can send a basic request to the server:

Example: List available tools

You can directly input the JSON-RPC payload:

{"method":"tools/list","params":{},"jsonrpc":"2.0","id":1}

Or, you can pipe the request using the echo command:

echo '{"method":"tools/list","params":{},"jsonrpc":"2.0","id":1}' | node build/index.js

Example: Call a specific tool (listnoditapi_categories)

echo '{"method":"tools/call","params":{"name":"list_nodit_api_categories","arguments":{}},"jsonrpc":"2.0","id":1}' | node build/index.js

You can also open and edit the mcp.json file directly at the following path:

• MacOS: ~/.cursor/mcp.json
• Windows: C:\Users\\.cursor\mcp.json

Add the following configuration to the mcpServers object. If you already have other MCP servers configured, separate each entry with a comma.

{
  "mcpServers": {
    "nodit": {
      "url": "https://mcp.nodit.io/sse?apiKey=INSERT_YOUR_API_KEY"
    }
  }
}

Once added, go back to MCP Tools in the Cursor interface and enable the nodit MCP by toggling it on. When the status shows “9 tools enabled” in green, the connection is complete.

Troubleshooting

Trouble running MCP via npx on Claude Desktop

If you are running the MCP server in combination with Claude Desktop or other tools that rely on a local Node.js installation, you may encounter issues due to:

• Multiple versions of Node.js installed (e.g., via Homebrew and package installer)
• Conflicting PATH environments
• Claude Desktop not recognizing the correct Node.js runtime

Follow the steps below to verify that Node.js 18+ is properly installed and recognized on your system.

1. Check your currently active Node.js version

Run the following command in your terminal to check the version:

node --version

You should see a version number starting with v18 or higher (e.g., v18.19.0).

If not, you may need to install a compatible version or switch to it.

> [!TIP] > Claude Desktop may not use the same Node.js version as your terminal. If you have multiple installations (e.g., via Homebrew, nvm, or direct installer), it may default to an unexpected version. > To list all common installation paths: > `` > # Homebrew installation > ls /usr/local/bin/node > ls /opt/homebrew/bin/node > > # nvm installations > ls ~/.nvm/versions/node/ > > # System installation > ls /usr/bin/node > ``

2. Install or switch to Node.js 18+ if needed

If you don’t have a compatible version, install Node.js using one of the following methods:

• Using Node.js official installer: Download from nodejs.org
• Using Homebrew (macOS):

bashbrew install node@20

• Using nvm (recommended for version management):

curl -o- https://raw.githubusercontent.com/nvm-sh/nvm/v0.39.0/install.sh | bash
nvm install 20
nvm use 20
nvm alias default 20

3. Check which Node.js version Claude Desktop uses

Claude Desktop inherits the PATH from your system environment. In your terminal, run:

which node

This displays the path of the Node.js binary currently active in your terminal. This is the path that Claude is likely to use when launched from that terminal.

4. Force Claude Desktop to use the correct Node.js version

• If you’re using nvm:

nvm use 18  # Set proper version 
nvm alias default 18

• If you’re using Homebrew, ensure it’s prioritized in your PATH:

export PATH="/opt/homebrew/bin:$PATH"  # for Apple Silicon
# or
export PATH="/usr/local/bin:$PATH"     # for Intel Macs

We recommend sticking to a single installation method (e.g., either nvm or Homebrew) to avoid version conflicts.

5. Restart Claude Desktop

After making changes, restart Claude Desktop to ensure it picks up the correct environment variables and Node.js version.

Scope & Limitations

Nodit MCP Server provides structured context to help LLM-based agents utilize Nodit's APIs effectively. Its responsibilities include:

• Structuring Nodit APIs (Node APIs, Web3 Data APIs) in an LLM-consumable format.
• Exposing endpoint details, input/output schemas, sample responses, and error handling guidelines.

However, the following are outside the MCP's control:

• API selection may vary depending on the LLM version (e.g., GPT-4, Claude 3), prompt engineering, or agent design.
• Interpretation of API responses or errors depends on the consuming LLM's reasoning capabilities.

Nodit MCP Server focuses on delivering accurate and structured API context, but does not guarantee the final reasoning outcomes or behavior of external LLMs.
