Search for similar or matching media across the indexed library. Provide a media_url or base64 media to find matches. Tiers: exact (hash match), quick (perceptual hash), perceptual (visual similarity), compositional (scene structure), full (all tiers). Returns results immediately.
Part of the Sidearm MCP server. Enforce policies on this tool with Intercept, the open-source MCP proxy.
AI agents call search_media to retrieve information from Sidearm 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 search_media 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.

Search for similar or matching media across the indexed library. Provide a media_url or base64 media to find matches. Tiers: exact (hash match), quick (perceptual hash), perceptual (visual similarity), compositional (scene structure), full (all tiers). Returns results immediately.. It is categorised as a Read tool in the Sidearm MCP Server, which means it retrieves data without modifying state.
Add a rule in your Intercept YAML policy under the tools section for search_media. You can allow, deny, rate-limit, or validate arguments. Then run Intercept as a proxy in front of the Sidearm MCP server.
search_media is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the search_media 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.
Set action: deny in the Intercept policy for search_media. 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.
search_media is provided by the Sidearm MCP server (sidearmdrm/sidearm). Intercept sits as a proxy in front of this server to enforce policies before tool calls reach the server.
