What is the AT Protocol MCP Server?

The AT Protocol MCP Server is a bridge connecting AI assistants to the AT Protocol ecosystem. It is built based on the Model Context Protocol standard, allowing AI assistants such as Claude and ChatGPT to securely access data and documents in the AT Protocol. Through this server, AI can query AT protocol specifications, documents, and manage resources such as AT keys.

How to use the AT Protocol MCP Server?

Before use, you need to configure the MCP server in the AI assistant client (such as Claude Desktop). After the configuration is completed, the AI assistant can access AT Protocol resources through natural language instructions, such as querying documents, obtaining key information, or viewing protocol specifications. The entire process does not require writing code and can be completed with simple conversations.

Applicable scenarios

It is suitable for developers and users who need to understand the technical details of the AT Protocol, or scenarios where AT keys and data need to be managed. For example: querying API documents when developing AT Protocol applications, managing personal data keys, learning AT protocol specifications, etc.

Main features

AT Protocol resource access
Provides access to AT Protocol specification documents and GitBook documents, including complete protocol descriptions and API references.
AT key management tool
Provides various tools to query and manage AT keys, supporting filtering by shared object, sharer, or regular expression.
Key-value operations
Can get the value of a specific AT key. In the future, full CRUD (Create, Read, Update, Delete) operations will be supported.
MCP standard compatibility
Fully complies with the Model Context Protocol specification and can be integrated with any AI assistant client that supports MCP.
Advantages
Access AT Protocol data without programming
Seamlessly integrate with mainstream AI assistants (such as Claude)
Provide structured access to AT protocol documents
Support flexible key query and filtering
Based on the standard MCP protocol, easy to expand
Limitations
Currently only supports read operations, and write functions are to be developed
Requires configuration of the AI assistant client
Depends on the AT Protocol network connection
Some advanced functions are still under development

How to use

Build the server
First, you need to compile the Dart source code into an executable file. Use the provided build command to generate the server program.
Configure the AI assistant client
Add MCP server settings to the configuration file of the AI assistant client (such as Claude Desktop).
Start and use
Restart the AI assistant client, and then you can access AT Protocol resources through natural language instructions.
Debugging and testing (optional)
Use the MCP Inspector tool to test and debug the server to ensure normal functionality.

Usage examples

Query development documents
When developers are building AT Protocol applications, they need to quickly query API documents and protocol specifications.
Manage personal data keys
Users want to view their AT keys and the sharing status of these keys.
Find keys of a specific type
Users need to find all AT keys related to contacts.
