WHAT IT DOES

What sdjwt_present does on Ainumbers Mcp Apps

AI agents use sdjwt_present to create or update resources in Ainumbers Mcp Apps, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Ainumbers Mcp Apps environment.

Parameter	Type	Required	Description
`aud`	string	—	KB-JWT audience. Supplying this adds a holder-binding KB-JWT to the presentation.
`nonce`	string	—	KB-JWT nonce. Auto-generated if aud is set and this is omitted.
`sd_jwt`	string	Yes	An SD-JWT string with all disclosures attached, as returned by sdjwt_issue.
`keep_keys`	array	—	Disclosure keys to keep in the presentation. Default: none (all disclosures redacted).
`issuer_did`	string	—	The sd_jwt's issuer did:key, to verify the JWS and populate verifier_view + receipt.

Parameters from the server's own tool schema.

RECOMMENDED RULE

The rule that runs sdjwt_present safely

PolicyLayer is an MCP gateway: it sits between your AI agents and Ainumbers Mcp Apps, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For sdjwt_present, this is the rule to start with:

sdjwt_present Rate-limited

sdjwt_present stays usable, but capped: an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.

FAQ

Questions about sdjwt_present

What does the sdjwt_present tool do? +

Builds a redacted presentation from an existing SD-JWT (as returned by sdjwt_issue), keeping only the listed disclosures. Pass aud to add a KB-JWT holder-binding (a fresh ephemeral holder key is generated per call). Pass issuer_did (the sd_jwt's "issuer" field) to also verify the JWS and return the verifier_view -- exactly the claim set a relying party would resolve -- plus an OCG receipt of the presentation activity. It is categorised as a Write tool in the Ainumbers Mcp Apps MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.

sdjwt_present accepts 5 parameters: aud, nonce, sd_jwt, keep_keys, issuer_did. Required: sd_jwt. The full parameter table on this page comes from the server's own tool schema.
