knowledge_schema

Melso Agents is available only internally or by private invitation. Agents-specific features require existing access. For the autónomo fiscal service, see Get started.

Create a collection with request_id, name and explicit scope, or read/mutate existing typed definitions with collection_id. Definition mutations require request_id, expected_revision and expected_schema_revision; property IDs and types stay stable. Availability: Autónomo / Empresa / Agents invitation. Catalog: Advanced (tools_search, then tools_call). The live catalog is authoritative: company type, membership, plan, connected apps and execution context can narrow this contract. Understand access.

Output

The selected collection schema or schema edit result. The result uses MCP content blocks; JSON payloads are encoded in text and may also appear in structuredContent. Check isError before reading a success payload. The server does not currently declare an outputSchema, so treat additional fields as extensible. Result handling.

Example

Use an OAuth access token issued for this MCP resource (a Run token for Run-only tools). Replace example identifiers with values from your own account. Write actions change data. First discover knowledge_schema with tools_search and confirm that the live schema permits these arguments.
