src_read

Use this when you need to read a specific file from an app's source snapshot. Returns file content with line-based pagination (offset/limit). Handles both text and binary files.

Accepts file system path (file_path); Single-target operation

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

AI agents call src_read to retrieve information from AppDeploy 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 src_read 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 src_read tool do? +

Use this when you need to read a specific file from an app's source snapshot. Returns file content with line-based pagination (offset/limit). Handles both text and binary files.. It is categorised as a Read tool in the AppDeploy MCP Server, which means it retrieves data without modifying state.

How do I enforce a policy on src_read? +

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

What risk level is src_read? +

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

Can I rate-limit src_read? +

Yes. Add a rate_limit block to the src_read 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 src_read completely? +

Set action: deny in the Intercept policy for src_read. 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 src_read? +

src_read is provided by the AppDeploy MCP server (appdeploy/deploy). Intercept sits as a proxy in front of this server to enforce policies before tool calls reach the server.
