What is the Chronicle MCP server?

Local MCP server to sync, clean, and index AI chat logs locally. Saves up to 40% context tokens. The chronicle mcp server wraps that behind the Model Context Protocol, so an assistant can use it through 14 defined tools rather than through you.

Its toolset

Everything the assistant can do here goes through one of these:

  • Non — TTY/Subprocesses**: Launches the stdio transport server for MCP clients
  • Linux — Follows the XDG base directory specification, resolving to ~/.config/
  • Cursor — Reads and writes configurations to ~/.cursor/mcp.json
  • macOS — ~/Library/Application Support/Code/User/globalStorage/saoudrizwan.claude-dev/settings/cline_mcp_settings.json
  • Windows — %APPDATA%/Code/User/globalStorage/saoudrizwan.claude-dev/settings/cline_mcp_settings.json
  • Trae — Resolves configuration to:
  • Description — Unified search and filter interface for local chat transcripts. Supports keyword, Okapi BM25 semantic, date range, and related chat lookups
  • Parameters — * query (str, default: ""): The search query string or keywords list
  • semantic — Standard semantic retrieval using Okapi BM25 scoring with exponential temporal decay
  • keyword — Exact string matching against terms in files
  • date_range — Filters files modified within a date interval (requires start_date and end_date)
  • related — Finds archives semantically close to a reference file

Adding it to your client

The server ships on PyPI as chronicle-mcp-server, so your MCP client can launch it on demand — there is no separate build step. Add the server block to your client's configuration, restart it, and the tools register themselves.

When to reach for it

Among the developer tooling options, the useful question is rarely "what can it do" but "what does it cost you to run" — permissions, credentials, and how much of your context its toolset consumes. Chronicle's toolset — Non, Linux, Cursor and 11 more — is a fair guide to whether it matches your workflow. It is maintained by Leviathan0x0; worth a glance at recent repository activity before you build anything load-bearing on it.

This entry was verified against Chronicle's own documentation before publication; SyncDev keeps the directory reviewed rather than auto-generated.

Caveats

  • It runs with your machine's permissions. That is convenient and also the reason to think about what you point it at before you approve a tool call.
  • With 14 tools registered it takes up a noticeable share of the context window; turn it off in projects that never touch Chronicle.
  • MCP clients confirm each tool call by default. Leave that on until you have watched what the chronicle mcp server does with a few real requests.

Frequently asked questions

It connects Chronicle to MCP-compatible AI assistants such as Claude and Cursor, exposing 14 tools (Non, Linux, Cursor, and more) that the assistant can call on your behalf. Instead of copying data back and forth by hand, the assistant works with Chronicle directly.
