Read, write, edit, search, and organize files in allowed directories.
Good to know
Access is restricted to configured directories; this is a reference server.

Connect an MCP client to local files, Git repositories, web pages, persistent memory, step-by-step reasoning, and timezone tools.
What you can do with Model Context Protocol servers
Retrieve web pages as Markdown or raw content and read long pages in chunks.
Good to know
Can reach local/internal IP addresses; callers must control which URLs are accessible.
Store, search, and update entities, observations, and relationships across chats.
Good to know
Uses a local knowledge graph file; configure persistent storage for container use.
Break problems into steps and record revisions or alternative reasoning branches.
Good to know
Receives thought steps from the client; it does not generate solutions on its own.
Look up the current time and convert times between IANA timezones.
Good to know
Requires valid IANA timezone names and Python 3.10+.
Inspect changes and commit history, stage files, commit changes, and manage Git branches.
1 other tool for: Inspect Git historyGood to know
Early development; requires Git and a local repository.
Exercise MCP client support for tools, prompts, resources, sampling, and progress notifications.
Good to know
A protocol demonstration and test server; its sample outputs are not real service data.
Before you upgrade Model Context Protocol servers
Newest firstSend POSIX paths to a Filesystem server running on POSIX; Windows drive paths are now rejected instead of being interpreted as relative filenames.
Read the evidence
Allow temporary-file creation and rename in the graph's parent directory; mount the storage directory rather than only the graph file when file bind mounts prevent atomic replacement.
Read the evidence
Use `mcp>=1.29.0,<2` for Fetch, Git, and Time; SDK 2.0 is not supported by these releases.

`read_media_file` returns non-image/audio binary data as an embedded `resource`, replacing the invalid top-level `blob` block; clients see `move_file` marked destructive.
Read the evidence
Keep staged paths inside the repository; remove leading dashes from revision, branch, base-branch, timestamp, and branch-filter values rejected by the new validation.
Relative file paths resolve against allowed directories instead of the server process's working directory.
Read the evidence
Read results omit storage-only `type` discriminators and expose only documented entity and relation fields.

Install MCP Python SDK `mcp>=1.23.0` for this Time release.
Read the evidence
Rediscover Everything's tools and prompts: e.g. `add` becomes `get-sum`, `printEnv` becomes `get-env`, and `sampleLLM` becomes `trigger-sampling-request`; use `demo://resource/` URIs instead of `test://static/resource/`.
Simulated logging and resource updates are off by default; enable them with `toggle-simulated-logging` and `toggle-subscriber-updates`.
`git_add` stages named files through `git add --`, enabling Git's normal filters and treating leading-dash filenames as paths.
Use `npm run start:stdio` instead of `npm start`; replace `zip` calls with `gzip-file-as-resource`, which accepts one URL/data URI and produces gzip rather than a multi-file ZIP.
Keep `repo_path` within the configured `--repository` directory; use valid refs without a leading dash for `git_diff` and `git_checkout`.
Default storage becomes `memory.jsonl`; an existing `memory.json` is renamed if the new file is absent. `MEMORY_FILE_PATH` overrides this migration.
Read the evidence
Subscribing to a resource no longer initiates an LLM sampling request.
Set `PYTHONIOENCODING=utf-8` in the Fetch server environment when Windows character-encoding problems cause timeouts.

Move files without silently replacing an existing destination.
Details
Filesystem now rejects occupied move destinations, creates nested directories, and preserves UTF-8 across partial reads. Memory saves replace the graph atomically instead of truncating its only copy first.
