A pluggable linter and fixer to enforce Protocol Buffer style and conventions.
Protolint MCP server is a locally run integration for AI assistants that speak the Model Context Protocol. A pluggable linter and fixer to enforce Protocol Buffer style and conventions.
protolint is the pluggable linting/fixing utility for Protocol Buffer files (proto2+proto3):
Installation goes through your MCP client rather than a global install: point it at protolint on npm and it is fetched when the client starts. The copy-paste blocks for Claude Desktop, Claude Code and Cursor are further down this page.
Once Protolint is connected, these are the calls the assistant has available:
Usage — For detailed documentation on how to use and integrate protolint's MCP server functionality, see the MCP documentationYou will need 2 environment variables: PROTOLINT_MIRROR_HOST, PROTOLINT_MIRROR_REMOTE_PATH. Keep credentials in your client's env block or a secrets manager rather than in a file you might commit.
This sits in the knowledge and memory group, where several servers overlap in what they claim to do but differ sharply once you actually set them up. Protolint's toolset — Usage — is a fair guide to whether it matches your workflow. It is maintained by yoheimuta; worth a glance at recent repository activity before you build anything load-bearing on it.
This entry was verified against Protolint's own documentation before publication; SyncDev keeps the directory reviewed rather than auto-generated.

A knowledge graph your assistant keeps between sessions — entities, relations and observations that persist.
Kill hallucinated APIs — version-accurate, up-to-date library documentation injected straight into context.
Your workspace, on speaking terms with AI — search, read and write Notion pages and databases.
A structured scratchpad for hard problems — stepwise reasoning with revisions, branches and visible logic.
Symbol-level code navigation, refactoring and memory for coding agents — the IDE brain your assistant has been missing.
Chat with your second brain — search, read and write vault notes through the Local REST API.
