Should I use this
Quality & Safety
Based on automated analysis of tool definitions and protocol compliance.
Context Cost
This is the approximate number of tokens consumed each time the server's tools are loaded into a model's context. Higher counts reduce the attention available for other tasks.

🟡create_result_reference(job_id, recipient_client_id, request_key, ttl_seconds)
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",
"properties": {
"job_id": {
"pattern": "^job_[a-f0-9]{32}$",
"type": "string"
},
"recipient_client_id": {
"description": "Public client identifier provided by the intended recipient through an authorized connection. Never their token.",
"pattern": "^client_[a-f0-9]{24}$",
"type": "string"
},
"request_key": {
"description": "Stable reference idempotency key. Reuse with identical job, recipient and requested lifetime.",
"pattern": "^[A-Za-z0-9][A-Za-z0-9_.-]{0,79}$",
"type": "string"
},
"ttl_seconds": {
"default": 900,
"description": "Reference lifetime, also bounded by the job and both access credentials' expiry.",
"maximum": 3600,
"minimum": 1,
"type": "integer"
}
},
"required": [
"recipient_client_id",
"job_id",
"request_key"
],
"additionalProperties": false
}Output Schema
{
"type": "object"
}🔴delete_job(job_id)
Delete the owner's stored result content. Retains an idempotency tombstone until expiry and does not reset quotas. Configure the owner's bearer access header.
Input Schema
{
"type": "object",
"properties": {
"job_id": {
"pattern": "^job_[a-f0-9]{32}$",
"type": "string"
}
},
"required": [
"job_id"
],
"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.
Input Schema
{
"type": "object",
"properties": {},
"additionalProperties": false
}Output Schema
{
"type": "object"
}🟢get_job(job_id)
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.
Input Schema
{
"type": "object",
"properties": {
"job_id": {
"pattern": "^job_[a-f0-9]{32}$",
"type": "string"
}
},
"required": [
"job_id"
],
"additionalProperties": false
}Output Schema
{
"type": "object"
}🟢get_result_reference(reference_id)
Retrieve the full shared result using the nominated recipient's configured bearer header. The reference alone grants no access. Expired, revoked or deleted results are unavailable.
Input Schema
{
"type": "object",
"properties": {
"reference_id": {
"pattern": "^ref_[a-f0-9]{32}$",
"type": "string"
}
},
"required": [
"reference_id"
],
"additionalProperties": false
}Output Schema
{
"type": "object"
}🟢resolve_capability(service_id)
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.
Input Schema
{
"type": "object",
"properties": {
"service_id": {
"description": "Exact canonical service_id from capability search, at most 96 UTF-8 bytes. Never a URL or credential.",

}
},
"required": [
"service_id"
],
"additionalProperties": false
}Output Schema
{
"type": "object"
}🔴revoke_result_reference(reference_id)
Owner revokes future retrieval through one shared result reference. Repeating this action is safe; previously downloaded copies cannot be recalled.
Input Schema
{
"type": "object",
"properties": {
"reference_id": {
"pattern": "^ref_[a-f0-9]{32}$",
"type": "string"

"reference_id"
],
"additionalProperties": false
}Output Schema
{
"type": "object"
}🟢search_capabilities(limit, query)
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.
Input Schema
{
"type": "object",
"properties": {
"limit": {
"default": 5,
"maximum": 5,
"minimum": 1,

}🟡submit_audit(csv_text, expected_records, request_key, requested_rules, rule, ...)
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.
