**The `codebase-memory-mcp` repository does not implement HTTP route linking across services because it is strictly a command-line installer, not a web service or distributed system.** It contains no HTTP endpoints, client libraries, or route definitions; the only network logic downloads release binaries from GitHub.

When developers search for how Codebase Memory handles inter-service HTTP communication, they may encounter the `codebase-memory-mcp` repository expecting to find routing logic or cross-service call-site mapping. However, this codebase serves a narrower purpose. Understanding its actual architecture prevents confusion about where service-to-service linking occurs in the broader Codebase Memory ecosystem.

## What codebase-memory-mcp Actually Implements

The `codebase-memory-mcp` repository functions as a binary distribution tool. It fetches pre-built executables from GitHub releases and handles local installation tasks such as unpacking archives and verifying checksums. It does not expose a web interface, implement microservice communication patterns, or contain the core Codebase Memory analysis engine.

Because the tool operates as a standalone CLI utility rather than a server, it requires no HTTP route definitions. The architecture consists entirely of local file system operations and a single outbound HTTP request to retrieve the appropriate binary for the target platform.

## The Only HTTP Logic: Downloading Release Archives

The repository's sole HTTP interaction resides in [`pkg/go/cmd/codebase-memory-mcp/main.go`](https://github.com/DeusData/codebase-memory-mcp/blob/main/pkg/go/cmd/codebase-memory-mcp/main.go) within the `download` function. This function constructs a URL pointing to the GitHub releases endpoint and retrieves the compressed binary archive.

### Download Function Implementation

The `download` function builds the release URL using repository metadata, version strings, and archive names, then executes an HTTP GET request:

```go
// Build the URL for the release archive
url := fmt.Sprintf(
    "https://github.com/%s/releases/download/v%s/%s",
    repo, version, archive,
)

// Download the archive (uses only HTTPS)
if err := httpGet(url, archivePath); err != nil {
    return fmt.Errorf("download failed: %w", err)
}

```

This represents the complete HTTP surface area of the repository. There are no POST handlers, route middleware, or client wrappers for service-to-service calls.

## Why Cross-Service Route Linking Is Absent

Linking HTTP routes to call sites across different services requires architectural components that this installer lacks:

- **Route definitions** — Declarative handlers using web frameworks (e.g., Gorilla Mux, Gin, or `net/http` ServeMux) to map URL paths to business logic.
- **Static analysis infrastructure** — Code scanning tools that identify endpoint declarations and their method signatures.
- **Call-site detection** — Logic that traces where services invoke HTTP clients (such as `requests` in Python or `axios` in JavaScript) to reach other services' endpoints.

None of these layers exist in `codebase-memory-mcp` because it is not a distributed system. The repository focuses exclusively on CLI installation workflows.

## What Would Be Required for Service-to-Service Linking

If Codebase Memory implements HTTP route linking across services, that logic resides in the binary installed by this tool, not in the installer itself. A typical implementation would include:

- **Server-side frameworks** defining RESTful or GraphQL endpoints
- **Client generation** or service discovery mechanisms that map service names to URLs
- **Distributed tracing** that correlates outgoing HTTP requests with their destination route handlers

The `codebase-memory-mcp` repository deliberately excludes these components to remain a lightweight distribution mechanism.

## Summary

- **No HTTP routes exist** in `codebase-memory-mcp`; it is a CLI installer, not a web service.
- All HTTP logic is confined to the `download` function in [`pkg/go/cmd/codebase-memory-mcp/main.go`](https://github.com/DeusData/codebase-memory-mcp/blob/main/pkg/go/cmd/codebase-memory-mcp/main.go), which fetches GitHub release archives.
- The repository contains **no client call sites**, **no static analysis of HTTP endpoints**, and **no cross-service linking mechanisms**.
- Service-to-service HTTP route linking would require web frameworks and analysis tools that are outside the scope of this installation utility.

## Frequently Asked Questions

### Does codebase-memory-mcp expose any HTTP endpoints?

No. The repository implements no web server, route handlers, or HTTP listeners. It is a standalone command-line utility that performs local file operations and downloads release artifacts from GitHub using HTTPS.

### Where is the HTTP route logic for Codebase Memory actually implemented?

The HTTP routing, API endpoints, and service-to-service communication logic reside within the Codebase Memory binary itself, which is distributed via GitHub releases and installed by this tool. That source code exists in a separate repository not covered by the `codebase-memory-mcp` installer package.

### Why does the installer need HTTP capabilities if it's not a service?

The installer uses HTTP solely to download the appropriate binary release from `https://github.com/DeusData/codebase-memory-mcp/releases/download/`. After completing the download, all subsequent operations involve local file system tasks such as unpacking archives and verifying checksums.

### Can this repository analyze HTTP routes in other codebases?

No. Despite the repository name suggesting memory or analysis capabilities, this specific package functions only as an installation wrapper. Any functionality for analyzing HTTP routes, linking call sites across services, or mapping API dependencies belongs to the installed binary, not this installer.
