UTCP Documentation MCP Server
Provides an example UTCP manual for the GitHub REST API, enabling AI agents to interact with repositories and issues through a standardized tool calling protocol.
Integrates with OpenAI's API to power an expert agent that answers questions about UTCP, leveraging LLM capabilities for documentation search and code generation.
Provides an example UTCP manual for the SendGrid email API, allowing AI agents to send emails with authentication via the SendGrid service.
Click on "Install Server".
Wait a few minutes for the server to deploy. Once ready, it will show a "Started" state.
In the chat, type
@followed by the MCP server name and your instructions, e.g., "@UTCP Documentation MCP ServerHow do I authenticate with bearer tokens?"
That's it! The server will respond to your query, and you can continue using it as needed.
Here is a step-by-step guide with screenshots.

SERVER_VERSION=1.0.0
LOG_LEVEL=info๐ ๏ธ Available Tools
๐ 1. Ask UTCP Expert (LLM Agent)
NEW! Ask an OpenAI-powered agent any question about UTCP:
{
"tool": "ask_utcp_expert",
"arguments": {
"question": "How do I authenticate with bearer tokens?"
}
}The agent:
Has deep knowledge of the entire UTCP specification
Retrieves relevant documentation automatically
Provides detailed explanations with code examples
Includes source references
Offers best practices and guidance
Example Questions:
"What is body_template and when should I use it?"
"Show me a complete HTTP tool example with OAuth2"
"How do I chain CLI commands together?"
"Why is my tool name failing validation?"
Requires: OpenAI API key (set OPENAI_API_KEY environment variable)
2. Search UTCP Documentation
Search the complete UTCP specification:
{
"tool": "search_utcp_docs",
"arguments": {
"query": "how to implement HTTP authentication",
"section": "protocols", // optional: introduction, protocols, guides, api
"limit": 5 // optional: max results
}
}Example Response:
# Search Results for "HTTP authentication"
## Result 1: HTTP Protocol Authentication
**Section:** protocols
**Relevance:** 45
Authentication in HTTP protocols can be configured using the auth field...3. Validate UTCP Manual
Validate your UTCP manual against the specification:
{
"tool": "validate_utcp_manual",
"arguments": {
"manual": {
"manual_version": "1.0.0",
"utcp_version": "1.0.1",
"tools": [...]
}
}
}Response:
โ
Valid UTCP Manual
The manual passes all validation checks and conforms to UTCP v1.0.1 specification.Or with errors:
โ Invalid UTCP Manual
## Errors
- /tools/0/name: Tool name "GetWeather" must use snake_case
- /tools/0/tool_call_template: HTTP template requires a URL
## Warnings
- /tools/0/description: Tool description should be at least 10 characters4. Generate UTCP Manual
Generate a UTCP manual template:
{
"tool": "generate_utcp_manual",
"arguments": {
"tool_name": "get_weather",
"description": "Get current weather for a location",
"protocol": "http",
"endpoint": "https://api.openweathermap.org/data/2.5/weather",
"method": "GET",
"parameters": {
"location": {
"type": "string",

"required": true
}
},
"include_auth": true
}
}Supported Protocols:
http- RESTful HTTP APIscli- Command-line toolsmcp- Model Context Protocol serverssse- Server-Sent Eventsstreamable_http- Streaming HTTP responses
5. Convert OpenAPI to UTCP

๐งช Usage Examples
Example 1: Creating a New UTCP Manual
// 1. Generate a template
const result = await callTool("generate_utcp_manual", {
tool_name: "send_email",
description: "Send an email via SendGrid API",
protocol: "http",
endpoint: "https://api.sendgrid.com/v3/mail/send",
method: "POST",
parameters: {
to: { type: "string", description: "Recipient email", required: true },
subject: { type: "string", description: "Email subject", required: true },
body: { type: "string", description: "Email body", required: true }
},
include_auth: true
});
// 2. Validate the generated manual
const validation = await callTool("validate_utcp_manual", {
manual: JSON.parse(result)
});
// 3. Get best practices for authentication
const practices = await callTool("get_best_practices", {
topic: "authentication"
});Example 2: Converting Existing OpenAPI Spec
// 1. Read your OpenAPI spec
const openApiSpec = JSON.parse(fs.readFileSync("api-spec.json"));
// 2. Convert to UTCP
const utcpManual = await callTool("convert_openapi_to_utcp", {
openapi_spec: openApiSpec
});
// 3. Validate the result
const validation = await callTool("validate_utcp_manual", {
manual: JSON.parse(utcpManual)
});Example 3: Searching Documentation
// Search for specific implementation details
const results = await callTool("search_utcp_docs", {
query: "how to handle streaming responses",
section: "protocols",
limit: 3
});
// Get an example to reference
const example = await callTool("get_utcp_examples", {
use_case: "github"
