What this MCP does

Discovers maintained data capabilities, processes and audits bounded CSV files, and securely shares or revokes access to stored agent results.

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.
Input schema
{'type': 'object', 'required': ['recipient_client_id', 'job_id', 'request_key'], 'properties': {'job_id': {'type': 'string', 'pattern': '^job_[a-f0-9]{32}$'}, 'request_key': {'type': 'string', 'pattern': '^[A-Za-z0-9][A-Za-z0-9_.-]{0,79}$', 'description': 'Stable reference idempotency key. Reuse with identical job, recipient and requested lifetime.'}, 'ttl_seconds': {'type': 'integer', 'default': 900, 'maximum': 3600, 'minimum': 1, 'description': "Reference lifetime, also bounded by the job and both access credentials' expiry."}, 'recipient_client_id': {'type': 'string', 'pattern': '^client_[a-f0-9]{24}$', 'description': 'Public client identifier provided by the intended recipient through an authorized connection. Never their token.'}}, 'additionalProperties': False}
Output schema
{'type': 'object'}
delete_job
Delete the owner's stored result content. Retains an idempotency tombstone until expiry and does not reset quotas. Configure the owner's bearer access header.
Destructive
Input schema
{'type': 'object', 'required': ['job_id'], 'properties': {'job_id': {'type': 'string', 'pattern': '^job_[a-f0-9]{32}$'}}, 'additionalProperties': False}
Output schema
{'type': 'object'}
get_catalog
Read public capabilities, free allowances, access bootstrap, privacy, retention and HTTP discovery routes. No access credential required.
Read only
Input schema
{'type': 'object', 'properties': {}, 'additionalProperties': False}
Output schema
{'type': 'object'}
get_job
Recover the original complete private CSV or audit result using its job_id and the owner's bearer access header. Results expire within 24 hours and cannot outlive access.
Read only
Input schema
{'type': 'object', 'required': ['job_id'], 'properties': {'job_id': {'type': 'string', 'pattern': '^job_[a-f0-9]{32}$'}}, 'additionalProperties': False}
Output schema
{'type': 'object'}
get_result_reference
Retrieve the full shared result using the nominated recipient's configured bearer header. The reference alone grants no access. Expired, revoked or deleted results are unavailable.
Read only
Input schema
{'type': 'object', 'required': ['reference_id'], 'properties': {'reference_id': {'type': 'string', 'pattern': '^ref_[a-f0-9]{32}$'}}, 'additionalProperties': False}
Output schema
{'type': 'object'}
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
Input schema
{'type': 'object', 'required': ['service_id'], 'properties': {'service_id': {'type': 'string', 'maxLength': 96, 'minLength': 1, 'description': 'Exact canonical service_id from capability search, at most 96 UTF-8 bytes. Never a URL or credential.'}}, 'additionalProperties': False}
Output schema
{'type': 'object'}
revoke_result_reference
Owner revokes future retrieval through one shared result reference. Repeating this action is safe; previously downloaded copies cannot be recalled.
Destructive
Input schema
{'type': 'object', 'required': ['reference_id'], 'properties': {'reference_id': {'type': 'string', 'pattern': '^ref_[a-f0-9]{32}$'}}, 'additionalProperties': False}
Output schema
{'type': 'object'}
search_capabilities
Find maintained Wever capabilities by a short task description or keyword. Returns fixed known services with connection details, contracts, limits and access steps. Does not execute work, grant permissions, search the whole web, or verify live availability.
Read only
Input schema
{'type': 'object', 'required': ['query'], 'properties': {'limit': {'type': 'integer', 'default': 5, 'maximum': 5, 'minimum': 1}, 'query': {'type': 'string', 'maxLength': 160, 'minLength': 1, 'description': 'Nonblank query of at most 160 UTF-8 bytes. Deterministic keyword matching over maintained Wever services only.'}}, 'additionalProperties': False}
Output schema
{'type': 'object'}
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.
Input schema
{'type': 'object', 'required': ['csv_text', 'expected_records', 'request_key'], 'properties': {'rule': {'type': 'object', 'default': {'kind': 'preserve_rows'}, 'description': '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': {'type': 'string', 'maxLength': 8192, 'description': 'At most 8192 UTF-8 bytes, 20 data records, 30 columns and 4096 UTF-8 bytes per cell.

Reuse only with identical input for the same capability.'}, 'requested_rules': {'type': 'array', 'items': {'type': 'string', 'maxLength': 200}, 'maxItems': 20, 'description': 'Descriptive requests, each at most 200 UTF-8 bytes. Every entry is reported unsupported; these do not authorize extra transformations.'}, 'source_metadata': {'type': 'object', 'properties': {'version': {'type': 'string', 'maxLength': 200}, 'encoding': {'type': 'string', 'maxLength': 200}, 'provider': {'type': 'string', 'maxLength': 200}}, 'description': 'Descriptive metadata only, each value at most 200 UTF-8 bytes. No URL fetching or encoding conversion.', 'additionalProperties': False}, 'expected_records': {'type': 'array', 'items': {'type': 'object', 'maxProperties': 30, 'propertyNames': {'maxLength': 4096}, 'additionalProperties': {'type': 'string', 'maxLength': 4096}}, 'maxItems': 20, 'description': 'Ordered expected records; field names and values are strings of at most 4096 UTF-8 bytes each.'}}, 'description': 'Complete canonical UTF-8 JSON payload at most 32768 bytes, HTTP body at most 48 KiB, nesting at most 32. The complete stored job envelope must fit 256 KiB or the request fails without storing a partial report.', 'additionalProperties': False}
Output schema
{'type': 'object'}
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.
Input schema
