Part of the Railway MCP Server MCP server. Enforce policies on this tool with Intercept, the open-source MCP proxy.

AI agents call project_list to retrieve information from Railway MCP Server without modifying any data. This is common in research, monitoring, and reporting workflows where the agent needs context before taking action. Because read operations don't change state, they are generally safe to allow without restrictions -- but you may still want rate limits to control API costs.

Even though project_list only reads data, uncontrolled read access can leak sensitive information or rack up API costs. An agent caught in a retry loop could make thousands of calls per minute. A rate limit gives you a safety net without blocking legitimate use.

Read-only tools are safe to allow by default. No rate limit needed unless you want to control costs.

What does the project_list tool do? +

[API] List all projects in your Railway account ⚡️ Best for: ✓ Getting an overview of all projects ✓ Finding project IDs ✓ Project discovery and management → Next steps: project_info, service_list → Related: project_create, project_delete. It is categorised as a Read tool in the Railway MCP Server MCP Server, which means it retrieves data without modifying state.

How do I enforce a policy on project_list? +

Add a rule in your Intercept YAML policy under the tools section for project_list. You can allow, deny, rate-limit, or validate arguments. Then run Intercept as a proxy in front of the Railway MCP Server MCP server.

What risk level is project_list? +

project_list is a Read tool with low risk. Read-only tools are generally safe to allow by default.

Can I rate-limit project_list? +

Yes. Add a rate_limit block to the project_list rule in your Intercept policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.

How do I block project_list completely? +

Set action: deny in the Intercept policy for project_list. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.

What MCP server provides project_list? +

project_list is provided by the Railway MCP Server MCP server (jason-tan-swe/railway-mcp). Intercept sits as a proxy in front of this server to enforce policies before tool calls reach the server.
