- What it is: Real-time Dynamic Tooling is a capability of the Model Context Protocol (MCP) that allows the list of available tools to change on the fly, without requiring a server restart or manual intervention. HasMCP supports this through the
tool_changedevent. - Why it’s important: In a real-world environment, the tools available to an LLM are not static.
- An API might be temporarily down for maintenance.
- A new API might be deployed.
- A user’s permissions might change, giving them access to new tools or revoking access to old ones.
- The structure of an API might change, with new parameters or different return values.
- How it works:
- HasMCP continuously monitors the health and status of the APIs it’s connected to.
- If it detects a change (e.g., an API goes offline, a new one comes online, or a user’s authentication status changes), it sends a
tool_changedevent to the LLM. - The LLM then knows that it needs to refresh its list of available tools.
- This ensures that the LLM is always working with the most current information.
- Key benefits:
- Agility: Your AI agents can adapt to changes in the environment in real-time.
- Resilience: If a tool becomes unavailable, the LLM will know not to use it, preventing errors.
- Scalability: New tools can be added to the system without any downtime.
- Security: If a user’s permissions are revoked, their access to tools is immediately cut off.
