Rail Connector MCP (SNComrade/Rail-Connector-MCP) is an MCP server listed on the M8ven Trust Index. M8ven has not graded it: we have no way to read this server ourselves. No publisher has claimed this listing.
Local MCP bridge that lets Codex operate local Claude Code sessions, including listing, starting, resuming, forking, prompting, and stopping conversations via the Remote Control CLI.
Caution. Specific findings reduced this grade. They are listed on the page. Grades reflect the full trust pyramid: code, verification depth, and reputation. New projects cap at C until adoption is earned.

CLAUDE_CONFIG_DIRComSpecRAIL_CONNECTOR_CLAUDE_PATHSystemRootTool annotations
No tools have read-only/destructive annotations
Add readOnlyHint or destructiveHint annotations to every tool so hosts can warn users before invoking.
All four hints declared on every tool
14/14 tools missing one or more hints — list_claude_sessions (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); get_claude_session (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); start_remote_control (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint), +11 more. OpenAI's directory rejects tools where any of the four hints are missing or non-boolean.
For every tool, set all four hints (readOnlyHint, destructiveHint, idempotentHint, openWorldHint) to explicit true/false values that match the handler’s actual behaviour.
Destructive tools are labelled
2 tools perform destructive updates without destructiveHint — archive_claude_session deletes at line 759 (fs.promises.unlink(lockFile)); unarchive_claude_session deletes at line 759 (fs.promises.unlink(lockFile))
Add destructiveHint:true to any tool whose handler calls .delete(), .upsert(), .update(), unlink, rm, DELETE, DROP, REPLACE INTO, or any operation that overwrites existing data.
Tool inputs are validated
13/14 tool handlers declare input schemas (93%)
Declare an inputSchema with zod/joi/yup on every tool definition.
Tests exist
No test files found
Add tests that exercise each declared tool.
Shell command execution
3 child_process/subprocess calls in production code — runs shell commands (src/index.js:1434, src/windows-broker-client.js:279, src/windows-broker.js:417)
Prefer library functions over shell-outs. If you must shell out, ensure all inputs are properly escaped.
