ctxlint MCP Server: Lint CLAUDE.md, AGENTS.md and MCP Configs

• Checks CLAUDE.md and AGENTS.md against your code

  Looks for stale file references, commands that do not exist, repeated or contradictory content, bad frontmatter and wasted tokens in your agent context files.

  Try: “Audit my CLAUDE.md and AGENTS.md for stale references.”

• Checks your MCP config files for mistakes

  Lints MCP server config files for wrong structure, hardcoded secrets, deprecated transports, wrong environment variable syntax and settings that differ between apps.

  Try: “Lint my MCP configs for secrets and mistakes.”

• Checks agent sessions and memory for problems

  Looks across your projects for diverged config files, stale or duplicate memory entries, command loops and, in Claude Code transcripts, repeated large file reads and other hazards.

  Try: “Audit my agent sessions for loops and stale memory.”

• Checks skill and subagent definitions

  Looks at skill and agent files for frontmatter problems, broken references, triggers that collide and unused tool limits.

  Try: “Audit my skills and subagents for broken references.”

  Files · ctxlint_skill_audit

• Checks that a path in a context file exists

  Says whether one file path named in a context file exists in the project and suggests a fix if not.

  Try: “Does src/utils/helpers.ts exist in this project?”

  Files · ctxlint_validate_path

• Counts tokens in your context files

  Gives token counts per file and in total, plus an estimate of waste from repeated content.

  Try: “How many tokens do my context files use?”

• Fixes broken file paths in context files

  Repairs broken paths in your context files using git history and fuzzy matching, and edits the files. Pass dryRun to preview the changes without writing.

  Try: “Fix broken paths in my context files, dry run first.”

Watch out for

• ctxlint_fix edits your context files

  It rewrites broken paths in files such as CLAUDE.md. Use dryRun first and check the result in git. npmjs.com

• It can read global configs and agent history

  ctxlint_mcp_audit can scan user-level MCP configs and ctxlint_session_audit reads session data and Claude Code transcripts, which can hold private material. npmjs.com

• Read-only tools declare it to your app

  The tools that only read are marked read-only, so some apps skip the confirmation prompt for them. github.com
