Trust breakdown (6 categories)

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 →

Endpoint Security46

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 not yet verified: we couldn't determine whether a plaintext access path exists. View diagnostics → Unverified
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 & Reachability100

Verified streamable-http transport via a live MCP handshake. View diagnostics → Pass

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

Capabilities0

Capabilities not yet verified: we couldn't read the endpoint's capabilities.Unverified

Unverified: 4 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.

Tool Tokens

knack_create_record Create a record ~165

MUTATES Knack data — creates a new record in an object. Knack API: POST /objects/{object_key}/records. Provide `fields` as an object keyed by field key, e.g. { "field_1": "Acme", "field_2": 100 }. Auto Increment / Formula / Equation fields are read-only and cannot be set. Returns the created record.

Input Output Examples

Name	Type	Req	Description
fields	object	yes	The record's field values keyed by field key, e.g. { "field_1": "Acme", "field_2": 100 }. Auto Increment / Formula / Equation fields are read-only and cannot be written.

No output schema declared.

No examples provided.

knack_delete_record Delete a record ~95

MUTATES Knack data — permanently DELETES a record (irreversible). Knack API: DELETE /objects/{object_key}/records/{record_id}. Knack returns { delete: true } on success.
