Codebase Memory Mcp
When to Use
Trigger phrases:
-
"codebase memory mcp"
-
"Navigating an unfamiliar codebase (first time exploring)"
-
"Understanding architecture: "What are the main modules and how do they connect?""
-
"Tracing call chains: "What calls handlePayment() and what does it call?""
-
Navigating an unfamiliar codebase (first time exploring)
-
Understanding architecture: "What are the main modules and how do they connect?"
-
Tracing call chains: "What calls handlePayment() and what does it call?"
-
Finding code by semantics: "Find all auth-related functions" (natural language)
-
Cross-file impact analysis: "What breaks if I change this function?"
-
When NOT to use: Single-file tasks (just read it), trivial codebases (<10 files), or when you already have full context
When NOT to Use
- When a simpler HTTP client would suffice
- For internal tools that do not need cross-platform compatibility
- When the tool is used by a single agent in a single context
Overview
Codebase Memory Mcp implements a Model Context Protocol server for Model Context Protocol.
Architecture
- Server — MCP-compliant server exposing tools and resources
- Transport — stdio or HTTP transport layer
- Tools — Callable functions with JSON Schema definitions
- Resources — Readable data sources with URI-based access
Setup
- Install the MCP server package
- Configure environment variables and credentials
- Register the server in MCP client configuration
- Test tool invocations and resource access
Configuration
- Server name and version
- Transport type (stdio, SSE, HTTP)
- Tool definitions with input/output schemas
- Resource URI patterns
- Authentication and rate limiting
Integration
- Compatible with Claude, Cursor, and other MCP clients
- Supports streaming responses for large payloads
- Handles errors with standard MCP error codes
Anti-Rationalization Table
| Rationalization | Reality |
|---|
| "I will just use curl" | MCP handles auth, retries, streaming, and type safety. Use the SDK. |
| "One mega-server is simpler" | Single-responsibility servers are easier to debug and maintain. |
| "MCP is just a wrapper" | MCP enables cross-platform tool sharing. It is infrastructure, not overhead. |
import { McpServer } from "@modelcontextprotocol/sdk";
const server = new McpServer({ name: "my-tools", version: "1.0.0" });
server.tool("search", { query: z.string() }, async ({ query }) => {
const results = await search(query);
return { content: [{ type: "text", text: JSON.stringify(results) }] };
});
Process
- Design — Define interface, identify patterns, plan implementation
- Implement — Write code following existing conventions, add tests
- Verify — Run tests, check integration, validate behavior
