What is the Platter MCP server?

Connect Platter to Claude, Cursor or any other MCP client and it stops being a tab you switch to. MCP server exposing Read, Write, Edit, Bash, Glob, Grep, and JS tools over stdio. The platter mcp server is what makes that connection.

What the server does

MCP server that exposes Read, Write, Edit, Bash, Glob, Grep, and JS tools over Stdio and StreamableHTTP transports. Built with Bun, compiles to standalone executables.

Available tools

The toolset is worth reading before you wire it up, because it tells you what the integration is really for:

  • read — Read file contents with pagination (offset/limit). Detects image files (JPEG, PNG, GIF, WebP) and returns metadata. Truncates text to 2000 lines or
  • write — Create or overwrite files. Auto-creates parent directories
  • edit — Find-and-replace with exact or fuzzy matching (normalizes smart quotes, dashes, and Unicode whitespace). Requires a unique match, or use replace_all
  • bash — Execute shell commands with optional timeout. Output truncated to last 2000 lines or 50KB
  • glob — Fast file pattern matching. Returns up to 500 paths matching a glob pattern (e.g. **/*.ts)
  • grep — Search file contents using ripgrep. Supports regex, file filtering, context lines, and multiple output
  • Restrictions — You can limit which tools are registered, which filesystem paths file tools can access, and which commands the bash tool can execute
  • Authentication — The Authentication tool exposed by this server
  • Limitations — The Limitations tool exposed by this server

Installation

ghcr.io/hadriangateway/platter on a container image is all you need. Most clients run it directly, so configuration is a few lines and a restart.

Credentials and setup notes

Configuration is passed through the environment: MCP_DANGEROUSLY_ALLOW_INSECURE_ISSUER_URL. Treat anything key-shaped as a real credential — scope it to the minimum the server needs, and rotate it if it ever lands in a shared config.

Where it fits

Among the file and storage access 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. Platter's toolset — read, write, edit and 6 more — is a fair guide to whether it matches your workflow. It is maintained by ScriptSmith; worth a glance at recent repository activity before you build anything load-bearing on it.

SyncDev reviews every entry in this directory against the project's own documentation before publishing, and revisits them as servers change.

Worth knowing first

  • 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 9 tools registered it takes up a noticeable share of the context window; turn it off in projects that never touch Platter.
  • Missing credentials fail quietly in some clients — if no tools show up, check the environment block first.
  • Keep per-call confirmation enabled while you learn its behaviour; it is the cheapest safeguard you have.

ToolWhat it does
readRead file contents with pagination (offset/limit). Detects image files (JPEG, PNG, GIF, WebP) and returns metadata. Truncates text to 2000 lines or 50KB.
writeCreate or overwrite files. Auto-creates parent directories.
editFind-and-replace with exact or fuzzy matching (normalizes smart quotes, dashes, and Unicode whitespace). Requires a unique match, or use replace_all for every occurrence (exact matches only). Returns a unified diff.
bashExecute shell commands with optional timeout. Output truncated to last 2000 lines or 50KB.
globFast file pattern matching. Returns up to 500 paths matching a glob pattern (e.g. **/*.ts).
grepSearch file contents using [ripgrep](https://github.com/BurntSushi/ripgrep). Supports regex, file filtering, context lines, and multiple output modes. Requires rg to be installed.
RestrictionsYou can limit which tools are registered, which filesystem paths file tools can access, and which commands the bash tool can execute.

Frequently asked questions

It connects Platter to MCP-compatible AI assistants such as Claude and Cursor, exposing 9 tools (read, write, edit, and more) that the assistant can call on your behalf. Instead of copying data back and forth by hand, the assistant works with Platter directly.
