How this component scores in each security and reliability category. Every signal is checked automatically against the live server, and we only credit what we can confirm. How we score → Why this is hard to score →
Endpoint Security57
- The endpoint's TLS certificate is valid, in date, and uses a strong key. View diagnostics → Pass
- Authorisation not fully verified: no authorisation is required to connect, but we couldn't read the tool list to see what that exposes. View diagnostics → Unverified
- HTTPS is enforced; there's no plaintext access path. View diagnostics → Pass
- HSTS check failed: the Strict-Transport-Security header is absent. See how to fix → View diagnostics → Fail
- DNSSEC check failed: this domain isn't protected by DNSSEC. See how to fix → View diagnostics → Fail
Transport & Reachability0
- Transport check failed: declared streamable-http, but the endpoint returned HTTP 429. See how to fix → View diagnostics → Fail
Schema Quality & AI Usability0
- Schema not yet verified: we couldn't read the endpoint's schema.Unverified
Stability & Change Management0
- Stability not yet verified: not enough scan history yet (needs a 30-day window).Unverified
Tool Coverage0
- Tool coverage not yet verified: we couldn't read the endpoint's tools.Unverified
Tool Safety0
- Tool safety not yet verified: we couldn't read the endpoint's tools.Unverified
Capabilities0

Unverified: 5 categories
Categories scored 0 because we could not verify them: authentication we do not have, an unreachable endpoint, or not enough scan history. We only credit what we can confirm.
How do I install the Sonnet 5 Agent MCP server?
Sonnet 5 Agent is a hosted endpoint at https://farm.llmotions.com/mcp/agents/sonnet-5-agent, so there is nothing to install locally. Ready-made configuration for Claude, Cursor, VS Code, Codex and 5 more is on this page, copied from each client's own documentation.

The tools this component advertises to a client, with an estimated token cost for each. Expand a tool to see its parameters and schema. The per-tool counts are indicative and are not scored directly; the schema's total context footprint is one signal in Schema Quality & AI Usability. A tool's description is untrusted text the model reads on every call, which is what makes this list a security surface and not just an inventory: how tool poisoning works →
agentfarm_agent_info Get Sonnet 5 Agent access information ~44
Returns this agent's identity, listed per-task price, MCP endpoint, and access URL. This metadata call does not run the model and does not require a bearer token.
Input schema present but exposes no named parameters.
No output schema declared.
No examples provided.
agentfarm_cancel_run Cancel AgentFarm run ~31
Cancels an authenticated queued or running run.
| Name | Type | Req | Description |
|---|---|---|---|
| run_id | string | yes | AgentFarm run identifier. |
No output schema declared.
No examples provided.
agentfarm_create_run Create a Sonnet 5 Agent run ~92
Queues an authenticated asynchronous task. This can consume paid model capacity. Poll with agentfarm_get_run_status, then read agentfarm_get_run_result.
| Name | Type | Req | Description |
|---|---|---|---|
| idempotency_key | string | – | Optional retry key; the same key and input return the original run. |

No output schema declared.
No examples provided.
agentfarm_get_run_result Get AgentFarm run result ~36
Returns the final summary and artifact download URLs for an authenticated run.
| Name | Type | Req | Description |
|---|---|---|---|
| run_id | string | yes | AgentFarm run identifier. |
