Compiler Explorer
Compile source and inspect assembly output without leaving the chat
Overview
What Compiler Explorer does
Compiler Explorer is the service behind godbolt.org, and this connector reaches the same public backend the website runs on. Source can be compiled and optionally executed across more than eighty languages and around two thousand compiler versions, curated libraries linked in, and assembly instructions looked up by name. Short URLs work both ways: a session can be turned into a godbolt.org link to hand to a person, and an existing link can be read back into source and compiler configuration. No authentication is required, and nothing is stored beyond what a short URL captures.
Tool surface
Seven tools: one compile, four list or lookup calls (list_compilers, list_languages, list_libraries, lookup_asm_instruction), and a short URL pair that writes a shareable link and reads one back into a compile request.
Availability
Where Compiler Explorer is listed
Compiler Explorer is listed in the Claude connectors directory only. Compiler Explorer LLC has no app under the same domain in the ChatGPT directory; 392 of the 3,150 products here are on both marketplaces, and this is not one of them.
The MCP server behind a Claude connector is usually the same server a ChatGPT app would need, so the absence is a distribution decision rather than a technical one.
Claude listing
In the Claude connectors directory
Compiler Explorer publishes 7 tools to Claude. That is a mid-sized surface: 33.4% of the 1,253 Claude-listed connectors expose fewer.
The median Claude-listed connector filed under Developer Tools publishes 13, so this one sits 6 tools below its bucket's median, 62nd of 95.
It falls in the 7-10 tools band, which holds 14.6% of the Claude directory.
Measured against the live endpoint
A direct call to the endpoint returned 7 tools, matching the 7 the listing publishes. Probed 2026-08-07.

Compiler Explorer publishes a remote MCP endpoint. Claude connects to it over HTTP; there is nothing to install locally.
Every connector in the Claude directory is remote, all 1,253 of them, so transport is not a differentiator there.

Compiler Explorer is community-listed in the Claude directory, the tier 770 of 1,253 connectors sit in (61.5%). It is the default for a self-published server, and says nothing either way about quality.
In the publisher's words
How Compiler Explorer LLC describes it
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.
