Compiler Explorer

Compiler Explorer (aka godbolt.org) is the canonical "what does my code compile to" tool. This MCP exposes the same backend Claude needs to compile and optionally execute source in 80+ languages across 2000+ compilers, link curated libraries, look up assembly instruction documentation, and round-trip godbolt.org/z/... short URLs to share sessions with humans. No auth required - it's the same public service the website runs on. Use it to verify what a snippet does, pick a compiler for a target architecture, or explain why one idiom compiles better than another.

Compiler Explorer in Developer Docs & Reference Search

0/100

Invisible

#12of 21competitors

This is the score for the Integration’s Primary Category, Developer Docs & Reference Search. Compiler Explorer's tools align with this Category, which is why we measure it here. Claude did not find it in connector search, show it in the connector picker, or invoke it in the measured contested Runs. That is why the score is 0.

Score explained

What does 0/100 mean?

0 is Compiler Explorer's rounded picker appearance rate. It appeared in the connector picker, or Claude invoked it directly, in 0% of contested conversations. All three measures are important to discoverability: Picked determines the headline score, Found shows how often Claude found Compiler Explorer in connector search, and Positioned shows where it appeared in the picker.

InvisibleBuriedEmergingCompetitiveWinning

Compiler Explorer is 10 points from Buried.

FoundDiagnostic

Whether Claude found your Connector in connector search. It must be Found before it can reach the picker, but the score counts picker appearances—not search results.

PickedMain score

How often your Connector appeared in the picker, or Claude invoked it directly, across contested conversations. This percentage is the Discoverability Score; the headline number is rounded.

PositionedDiagnostic

What position your Connector appeared in when it was shown in the picker. This shows prominence, but it does not affect the score.

Tools

7 tools agents can invoke

Compile source code and return assembly output, stdout, and stderr
Create a Compiler Explorer short URL for sharing code with compiler settings
Retrieve source and compiler config from a CE short URL. Compiler entries are returned in the `compile` tool's shape ({compiler, options, libraries:[{id, version}]}). Multi-pane shortlinks (executors, conformance views, CMake trees, per-compiler filters/tools) are flattened — only the basic compile inputs survive.
List available compilers, optionally filtered by language
List supported languages. Each entry has `defaultCompiler` and `compilerCount`.
List available libraries for a given programming language
Look up documentation for an assembly instruction

Compiler Explorer FAQ

How do I improve a Community connector's discoverability?

The levers are the listing surface agents actually read: names, descriptions, keywords, tool metadata, and registry health. Which lever matters depends on where discovery breaks, which is what continuous measurement shows.
