Adds a "Using with Other MCP Clients" section to the README with copy-pastable config for opencode, Cursor, LangChain (MultiServerMCPClient), and the Claude Agent SDK, plus a generic stdio-MCP fallback. Each client gets the exact field names it actually expects (the existing README only documented the Claude Code / ~/.claude.json shape). Notes: - The CodeGraph MCP server speaks stdio only, so the LangChain example explicitly passes `transport: "stdio"` (the issue reporter had been trying to use SSE config) and there's a closing note pointing SSE-only clients at supergateway as a bridge. - The generic-fallback section documents the `--path` flag for clients that don't send a `rootUri` in the initialize request. Closes colbymchenry#65, colbymchenry#79. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>

Summary\n\nAdds a "Using with Other MCP Clients" section to the README. The current README only documents the Claude Code /
~/.claude.jsonsetup, which leaves users of other MCP clients (opencode, Cursor, LangChain, the Anthropic Agent SDK) guessing at the right config shape — that's what issues colbymchenry#65 and colbymchenry#79 ask for.\n\nCloses colbymchenry#65, colbymchenry#79.\n\n## What's added\n\nA new section right after the existing MCP Tools table, covering five client shapes:\n\n- opencode —opencode.jsonmcp.<name>block withtype: "local"+commandarray\n- Cursor —~/.cursor/mcp.jsonmcpServers.<name>block (Anthropic-style stdio shape)\n- LangChain (MultiServerMCPClient) — Python dict withcommand/args/transport: "stdio". Issue colbymchenry#65 was specifically tripping on SSE config — the section calls out that the server is stdio-only.\n- Claude Agent SDK — PythonClaudeAgentOptions(mcp_servers=...)withallowed_tools=["mcp__codegraph__*"]\n- Generic stdio MCP fallback — a 3-row table (command,args,transport) for any other client, plus a note about--pathfor clients that don't sendrootUriin the initialize request\n\nA closing note points SSE-only clients at supergateway as a stdio→SSE bridge.\n\n## Test plan\n\n- [x] Reviewed the rendered Markdown locally\n- [x] Verified the field names against each client's actual docs:\n - opencode: https://opencode.ai/docs/mcp-servers/\n - Claude Agent SDK: https://code.claude.com/docs/en/agent-sdk/mcp\n - LangChain: langchain-ai/langchain-mcp-adapters README\n- [x] Verifiedcodegraph serve --mcp --path <dir>flag exists insrc/bin/codegraph.ts:1031\n- [x] Verified the server readsrootUrifrom theinitializerequest insrc/mcp/index.ts:257\n\n🤖 Generated with Claude Code\nCopied from colbymchenry/codegraph#96
