Svn Agent

Strict SVN Model Context Protocol server for agent-safe status, diff, EOL diagnosis, precommit checks, and guarded SVN mutations.

The implementation contract lives in docs/SPEC.md. Version 1.0.0 is the first public open-source release and can prepare a self-contained local runtime bundle under releases/v1.0.0.

Requirements: Windows, Node.js 20 or newer, Git, and access to the public npm registry. The bundled SlikSVN and dos2unix runtime payload is Windows-only.

Quick Start

git clone https://github.com/shrishailrana-maker/svn-agent-mcp-v1.git
cd svn-agent-mcp-v1
npm install
npm run prepare:local
npm test

Agent Setup From GitHub

Tell an agent:

Get the SVN MCP from https://github.com/shrishailrana-maker/svn-agent-mcp-v1, clone it to C:\MCP\svn-agent-mcp-v1, run npm install, run npm run prepare:local, then configure the MCP command as node C:\MCP\svn-agent-mcp-v1\current\dist\index.js.

The setup commands are:

git clone https://github.com/shrishailrana-maker/svn-agent-mcp-v1.git C:\MCP\svn-agent-mcp-v1
cd C:\MCP\svn-agent-mcp-v1
npm install
npm run prepare:local

Then configure the MCP client to run:

node C:\MCP\svn-agent-mcp-v1\current\dist\index.js

Claude Desktop Config Example

Add this under mcpServers:

{
  "mcpServers": {
    "svn": {
      "command": "node",
      "args": ["C:\\MCP\\svn-agent-mcp-v1\\current\\dist\\index.js"]
    }
  }
}

Codex Config Example

[mcp_servers.svn]
command = "node"
args = ["C:\\MCP\\svn-agent-mcp-v1\\current\\dist\\index.js"]
startup_timeout_sec = 120

Restart the MCP client after changing the config.

Start The MCP

For development from this working copy:

cd <path-to-svn-agent-mcp-v1>
npm install
npm run prepare:local
node .\current\dist\index.js

The source tree includes bin/ with the full SlikSVN bin payload plus the full dos2unix bin payload. Releases copy that folder to current/bin, so normal Windows clients do not need to locate or install svn, svnversion, svnadmin, dos2unix, unix2dos, or their required DLLs. See THIRD_PARTY_NOTICES.md and THIRD_PARTY_CHECKSUMS.txt for bundled binary notices and SHA256 hashes.

Plug-And-Play Client Config

Register the MCP once globally. Do not set cwd and do not set environment variables:

Generic client example:

{
  "mcpServers": {
    "svn": {
      "command": "node",
      "args": ["C:\\MCP\\svn-agent-mcp-v1\\current\\dist\\index.js"]
    }
  }
}

The MCP is not tied to one SVN checkout. If a tool call supplies absolute paths and omits cwd, the server finds the nearest SVN working copy for those paths. Relative paths require explicit per-call cwd.

Client registration is static: configure the MCP once, and working-copy discovery happens per tool call. The server does not rewrite client configuration at runtime.

Environment variables are not required for normal use. They are development/test escape hatches only: SVN_AGENT_BIN_DIR, SVN_AGENT_SVN_PATH, SVN_AGENT_DOS2UNIX_DIR, SVN_AGENT_TIMEOUT_MS, and SVN_AGENT_MAX_DIFF_LINES.

Commands

Command	Description
npm run dev	Run the TypeScript entry point during development
npm run typecheck	Check TypeScript without emitting build output
npm run build	Compile src/ into dist/
npm test	Run the Jest test suite
npm run prepare:local	Build and prepare the local current runtime
npm run release:prepare	Copy dist/ and bin/ into releases/v<version> and repoint current
npm run clean	Remove root dist/ with the Node clean script

Operator Diagnostics

Use svn_self_check to verify the MCP package, current release pointer, bundled binaries, and release scripts. Use svn_diagnose on a working-copy path when SVN itself is acting strange; it checks local status, remote status, HEAD info, latest log reachability, and returns actionable notes for authentication, network, lock, and working-copy database failures.

For SVN property work, use svn_propget and guarded svn_propset instead of raw svn propget/svn propset. svn_propset_eol_style remains the safer shortcut for svn:eol-style normalization.

Usage Model

Register one global MCP server and use explicit paths or per-call cwd values when working across SVN checkouts. The server does not assume a product name, project name, or fixed working copy.
