What transport does it use?

Streamable HTTP at https://mcp.example4.ai/mcp.

Does it require local clones?

No, all data is served remotely with no cloning or disk usage.

What is the xmp4 — Semantic Code Intelligence MCP server?

The server eliminates token waste from traditional grep-and-clone workflows by serving precise, SCIP-resolved data through a streamable HTTP transport. It supports Tier 1 languages including Python, TypeScript, Java, Rust, C#, and PHP with full semantic features.

Benchmarks show xmp4 uses dramatically fewer tokens than GitMCP while returning real source bodies and caller graphs. Setup requires only adding the endpoint to an MCP client config.

Install & connect

Add this to your MCP client config. Pick your client below and copy.

{
  "mcpServers": {
    "xmp4": {
      "url": "https://mcp.example4.ai/mcp"
    }
  }
}

Tools it exposes

15 tools your AI client can call once connected.

xmp4_projects— List available indexed projects

xmp4_search— Search for symbols across libraries

xmp4_info— Retrieve signature and metadata for a symbol

xmp4_usages— Find usages of a symbol

xmp4_callers— List real callers of a symbol

xmp4_callees— List callees of a symbol

xmp4_hierarchy— Show type hierarchy for a symbol

xmp4_outline— Get outline of a file or symbol

xmp4_source— Fetch the source body of a symbol

xmp4_tests_for— Find tests related to a symbol

xmp4_deps— Show dependencies of a symbol or project

xmp4_symbol_at— Resolve symbol at a location

xmp4_view— View raw file excerpt by line range

xmp4_grep— Server-side regex search when semantics insufficient

xmp4_guide— Return versioned skill pointer and cheatsheet

Example prompts

Once connected, try asking your AI client:

“Using xmp4, find the Flask class and list its usages.

“Show me the callers of wsgi_app in the flask repository.

“Get the signature, body, and type hierarchy for a symbol in django.

“Search for tests related to a specific function using xmp4 tools.

Security & permissions

Remote hosted service accessed via HTTPS streamable HTTP; no local filesystem access or API keys required.

What you can do with xmp4 — Semantic Code Intelligence

Find symbol callers

Ask for real callers of Flask.wsgi_app and receive SCIP-resolved results instead of noisy grep matches.

Explore type hierarchies

Query inheritance and interface relationships across large OSS codebases without cloning repositories.

Efficient code navigation

Retrieve exact source bodies and outlines for symbols in Django, Tokio, or Spring Boot using minimal tokens.

How to use xmp4 — Semantic Code Intelligence

1Add the server URL https://mcp.example4.ai/mcp to your client's mcpServers config.
2Restart the AI client after updating the configuration.
3Optionally install the xmp4 skill by fetching the SKILL.md file.
4Test with a prompt asking to find a symbol or its callers.
5Use xmp4_guide for version-specific usage instructions.
