Search the Anthropic product changelog corpus. Use mode=hybrid (default, requires embeddings) for semantic/conceptual queries; mode=fts for exact keyword/phrase matching. Returns ranked changelog bullets with product+version+date metadata.
AI agents call search to retrieve information from Claude Synergy without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves and queries static changelog data without side effects. It supports two search modes (hybrid semantic search and full-text search) but both are read-only operations over a mirrored, queryable corpus. There is no capability to create, modify, delete, or execute code/commands.
From the tool's definition Tool description explicitly states it 'Search[es] the Anthropic product changelog corpus' and 'Returns ranked changelog bullets with product+version+date metadata.' The verb 'search' combined with 'returns' indicates data retrieval only.
Attacks that exploit this kind of access
Search the Anthropic product changelog corpus. Use mode=hybrid (default, requires embeddings) for semantic/conceptual queries; mode=fts for exact keyword/phrase matching. Returns ranked changelog bullets with product+version+date metadata. It is categorised as a Read tool in the Claude Synergy MCP Server, which means it retrieves data without modifying state.
Register the Claude Synergy MCP server in PolicyLayer and add a rule for search: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches Claude Synergy. Nothing to install.
search 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 rule in your PolicyLayer 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 PolicyLayer policy for search. 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 is provided by the Claude Synergy MCP server (mcp-tool-shop-org/claude-synergy). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
