Aptu Coder MCP Server

A Model Context Protocol (MCP) code-intelligence server that gives AI coding agents pre-parsed symbol tables and call graphs instead of raw file bytes, cutting token usage by up to 59% (see Benchmarks ). OpenSSF silver certified: fewer than 1% of open source projects reach this level. Its 7 documented tools cluster into analyze, update, run & execute.

People who work with code analysis, developer tools and tree sitter and want it reachable from Claude, Cursor, VS Code, or another MCP client. The project is written in Rust.

03 · What Aptu Coder can do

Prose above is summarized from the project's README and registry record - no invented capabilities.

What you can build

With this server connected, an agent can call graph for a named symbol across a directory, create or overwrite a file, replace a unique exact text block or all non-overlapping occurrences (replace_all=true), and run a shell command.

Capability map

Tools grouped from the project's README - what Aptu Coder lets an agent do.

Analyze

4 tools - e.g. Directory tree with LOC, function, and class counts; respects .gitignore; file paths in the output are relative to the working directory; Functions, classes, and imports with signatures and line ranges…

update

2 tools - e.g. Create or overwrite a file; creates parent directories; Replace a unique exact text block or all non-overlapping occurrences (replace_all=true); errors if zero or multiple matches; empty new_text deletes…

run & execute

1 tool - e.g. Run a shell command; returns stdout, stderr, exit code; output capped and filtered; the command is killed when the request is cancelled; server-owned post-exit
