Nothing to run from here
Compiler Explorer is installed from its publisher's own source and answers where it runs, so this marketplace is not in the path of a single call. There is no address here to send one to, and a panel that pretended otherwise would be showing you an answer we made up. Install it and call it from your own client — the Installation tab has the entry for each one.

What it does
Compile code with thousands of compilers, inspect the assembly, and share godbolt.org links
Quickstart
# 1 — add it to Claude Code
claude mcp add --scope user --transport http compiler-explorer-mcp https://godbolt.org/mcp
# 2 — ask your agent for something these tools do
# compile, list_compilers, list_languages and 4 more
Compiler Explorer costs nothing on mcprush: there is no plan to choose here, no cap to set and nothing mcprush can bill you for.

Installation
Where are you running it?
Every route below installs the same thing and ends at the same approval screen. Nothing here runs on your machine and nothing runs on ours: this server answers at its publisher’s own address, and what you install is the connection straight to it.
Claude Codedeclared by this listing
This is a public server: it answers at its publisher’s own address and this marketplace is not in the path. Claude Code registers it in one command; --scope user makes it available in every project. The transport below is http, as the publisher's own manifest declares it.
claude mcp add --scope user --transport http compiler-explorer-mcp https://godbolt.org/mcpReconnect, or start a new session, and the tools appear in the model’s tool list.
Free on mcprush, and it answers at its publisher’s own address: this marketplace is not in the path, so there is no key of ours to hold and no card to add.
What it writes
One config entry pointing straight at the publisher’s own address — this marketplace is not in the path, and nothing from this listing executes on your machine.
What you approve
7 tools, with what each one reads, writes and reaches shown before you agree — the same list on every route above. Read the tool surface.

Compile source code and return assembly output, stdout, and stderr
| Parameter | Type | Required | Notes |
|---|---|---|---|
| source | string | yes | Source code to compile |
| language | string | yes | Language ID (e.g. "c++", "c", "rust", "python") |
| compiler | string | no | Compiler ID from list_compilers (e.g. "g161"). If omitted, uses the language's defaultCompiler from list_languages. |
| options | string | no | Compiler flags (e.g. "-O2 -std=c++20 -Wall") |
| execute | boolean | no | Run the program instead of returning assembly. asm becomes empty; runtime output goes to top-level stdout/stderr; compile diagnostics move to buildResult.stdout/stderr. |
| stdin | string | no | Standard input for execution (requires execute=true) |
| filters | object | no | Output filters |
| libraries | array | no | Libraries to link. |
| maxAsmLines | integer | no | Cap asm output (default 500 lines). |
| maxStdoutLines | integer | no | Cap each stdout stream — compile and execute separately (default 100). |
| maxStderrLines | integer | no | Cap each stderr stream — compile and execute separately (default 100). |
List available compilers, optionally filtered by language
| Parameter | Type | Required | Notes |
|---|---|---|---|
| language | string | no | Language ID to filter by (e.g. "c++", "rust", "python") |
| instructionSet | string | no | Target architecture filter. Combine with latestPerMajor: true for "newest X for arch Y" (e.g. {language:"c++", instructionSet:"amd64", latestPerMajor:true}). |
| match | string | no | Case-insensitive AND-of-tokens filter on id and name. Punctuation splits tokens; numeric tokens match whole-word ("gcc 14.1" matches "14.1.0" not "14.10"); alphanumeric tokens substring-match ("g14" m |
| maxResults | integer | no | Cap full-detail entries (default 25). Beyond the cap, degrades to lean (id+name only) with a refinement hint. |
| lean | boolean | no | Force id+name only, regardless of count. Useful to browse the catalog before drilling in. |
| latestPerMajor | boolean | no | "Newest X" filter. By release track (stable/nightly/prerelease/experimental): newest stable per (language, instructionSet, semver major); all nightly + prerelease; experimental skipped unless `include |
| includeExperimental | boolean | no | With latestPerMajor: true, also include experimental compilers (c++ proposal forks, llvm-mos platform variants). Off by default — bloats "newest X" answers. |
List supported languages. Each entry has defaultCompiler and compilerCount.
No parameter schema on file.
List available libraries for a given programming language
| Parameter | Type | Required | Notes |
|---|---|---|---|
| language | string | yes | Language ID (e.g. "c++", "rust") |
| match | string | no | Case-insensitive AND-of-tokens filter on id, name, and version strings (so "boost 1.88" finds Boost when one of its versions matches 1.88.x). Numeric tokens match version-prefix; alphanumeric substrin |
| maxResults | integer | no | Cap full-detail entries (default 25). Beyond the cap, degrades to lean (id+name only) with a refinement hint. |
| lean | boolean | no | Force id+name only, regardless of count. Useful to browse the catalog before drilling in. |
Look up documentation for an assembly instruction
| Parameter | Type | Required | Notes |
|---|---|---|---|
| instruction_set | string | yes | Instruction set architecture (no default — must match the asm dialect being looked up). |
| opcode | string | yes | Assembly instruction mnemonic (e.g. "MOV", "ADD", "JMP") |
Create a Compiler Explorer short URL for sharing code with compiler settings
| Parameter | Type | Required | Notes |
|---|---|---|---|
| source | string | yes | Source code |
| language | string | yes | Language ID (e.g. "c++", "c", "rust") |
| compiler | string | yes | Compiler ID from list_compilers (e.g. "g161", "clang_trunk") |
| options | string | no | Compiler flags (e.g. "-O2 -std=c++20") |
| libraries | array | no | Libraries to include. |
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.
| Parameter | Type | Required | Notes |
|---|---|---|---|
| id | string | yes | Short link ID or full URL (e.g. "G38YP7eW4" or "https://godbolt.org/z/G38YP7eW4") |

—Grade not published
No rule-by-rule report on file for this release
Two independent axes, because powerful and malicious are different questions. The grade is threat only. The capability level is blast radius, and it is never a penalty on the grade — it is priced as one subtract-only term in the score, where you can see it.
This listing is an address its publisher runs, and you connect to it directly — this marketplace is not in the path. The scanner reads packages and public source, and an address is neither: the repository linked on this page is where this record was collected from, not a copy of what the address serves, so it is not graded in its place. So there is no grade — not a withheld one, an unmeasured one.
Release history
This is an address its publisher runs: which release it serves is theirs to choose, so there is nothing here to pin. The history below is for reading; the current release on file is 1.0.0.

Who can review
One review per account, from a signed-in account that does not publish this listing. Nothing else is asked — you can say what you think before you install it. Publishers can reply once per review, and a review can be edited or deleted by whoever wrote it.
Sign in to write one
Any signed-in account that does not publish Compiler Explorer can review it, once — before installing it or after. A review from an account that has installed it is marked as one.
No reviews yet
Nobody has reviewed this listing. The rating on the card is the mean of the reviews written here and nothing else, so there is no rating until somebody writes the first — which takes a signed-in account that does not publish it, and nothing else.
