ACP clients pass MCP server definitions in session/new, load_session,
resume_session, and fork_session. Previously these were accepted but
silently ignored — the agent never connected to them.
This wires the mcp_servers parameter into the existing MCP registration
pipeline (tools/mcp_tool.py) so client-provided servers are connected,
their tools discovered, and the agent's tool surface refreshed before
the first prompt.
Changes:
tools/mcp_tool.py:
- Extract sanitize_mcp_name_component() to replace all non-[A-Za-z0-9_]
characters (fixes crash when server names contain / or other chars
that violate provider tool-name validation rules)
- Use it in _convert_mcp_schema, _sync_mcp_toolsets, _build_utility_schemas
- Extract register_mcp_servers(servers: dict) as a public API that takes
an explicit {name: config} map. discover_mcp_tools() becomes a thin
wrapper that loads config.yaml and calls register_mcp_servers()
acp_adapter/server.py:
- Add _register_session_mcp_servers() which converts ACP McpServerStdio /
McpServerHttp / McpServerSse objects to Hermes MCP config dicts,
registers them via asyncio.to_thread (avoids blocking the ACP event
loop), then rebuilds agent.tools, valid_tool_names, and invalidates
the cached system prompt
- Call it from new_session, load_session, resume_session, fork_session
Tested with Eden (theproxycompany.com) as ACP client — 5 MCP servers
(HTTP + stdio) registered successfully, 110 tools available to the agent.
