Authorization (required)

Bearer access token from POST /v1/access. Enter Bearer followed by your token; keep it private. Access expires after 24 hours.

Requests go through mcptry because browsers can't call most MCP servers directly. Header values are sent to the server for that request only and are never stored or logged.

Tool list from our last check. Connect live to refresh it.

create_result_reference

Authorize one recipient client_id to read one owned result with its own credential. Returns a credential-free, expiring reference for agent handoff. Owner access stays in the configured header. Requires explicit intended recipient; no permission to other jobs, deletion or resharing.

job_idstring, required

request_keystring, required

Stable reference idempotency key. Reuse with identical job, recipient and requested lifetime.

recipient_client_idstring, required

Public client identifier provided by the intended recipient through an authorized connection. Never their token.

ttl_secondsinteger

Reference lifetime, also bounded by the job and both access credentials' expiry.

This tool isn't marked read-only, so it may change something on the server or in an account you connected.

    }
  },

resolve_capability

Resolve an exact canonical Wever service_id to its maintained connection metadata, contract, limits and access steps. Unknown identities are rejected; no caller-supplied URL is fetched. Does not verify live availability or authorize execution.

read-only

Argument	Type	Description
service_id*	string	Exact canonical service_id from capability search, at most 96 UTF-8 bytes. Never a URL or credential.

    }
  },
  "additionalProperties": false
}

submit_audit

Audit bounded CSV against caller-supplied expected records with explicit grouping, exact source references, lineage and integrity checks. A completed audit can report mismatches or blocked parsing. Inspect result.status, comparison, ambiguities and unsupported rules. No factual verification or inferred transformations.

Argument	Type	Description
rule	object	Supports {kind: preserve_rows} or {kind: explicit_groups, groups: [{source_records: [1,2], concatenate: {column: separator}}]}. Source indexes are one-based and exclude the header. Invalid or unsupported rule options are findings with preserving fallback. No grouping is inferred. At most 8192 UTF-8 bytes.
csv_text*	string	At most 8192 UTF-8 bytes, 20 data records, 30 columns and 4096 UTF-8 bytes per cell. Exact strings are preserved.
request_key*	string	Stable idempotency key shared across CSV and audit. Reuse only with identical input for the same capability.
requested_rules	array	Descriptive requests, each at most 200 UTF-8 bytes. Every entry is reported unsupported; these do not authorize extra transformations.
source_metadata	object	Descriptive metadata only, each value at most 200 UTF-8 bytes. No URL fetching or encoding conversion.
expected_records*	array	Ordered expected records; field names and values are strings of at most 4096 UTF-8 bytes each.

submit_csv

Normalize bounded CSV using explicit column rules. Returns a complete private job and checked CSV. Configure bearer access in the client header. Reuse request_key on retries.

Argument	Type	Description
schema*	object
csv_text*	string	At most 16 KiB UTF-8 and 100 data records
request_key*	string	Stable idempotency key shared across CSV and audit. Reuse only with identical input for the same capability.
