> ## Agent Instructions
> Melso product MCP: https://melso.ai/api/mcp (OAuth; one company per grant). REST: https://melso.ai. Documentation-search MCP: https://docs.melso.ai/mcp. The docs search server does not act on customer accounts.
>
> Use the live tool schema and respect company membership. Ask the person to authorize the exact fiscal document version in the signed-in app. A professional prepares and files included returns after authorization; AI does not file alone. A prepared file or approval receipt is not evidence of filing. Never claim completion from an accepted Task or Run. Keep credentials out of chat and logs. Agents features are internal or by private invitation.

# tools_search

> Input, output and examples for the tools_search MCP tool.

<Info>Melso Agents is available only internally or by private invitation. Agents-specific features require existing access. For the autónomo fiscal service, see [Get started](/essentials/quickstart).</Info>

Find advanced Melso tools by name or task, then call the exact returned name with tools\_call. Eligible member OAuth connections can also discover tools for connected apps.

**Availability:** Autónomo / Empresa / Agents invitation.

**Catalog:** Core (`tools/list`).

The live catalog is authoritative: company type, membership, plan, connected apps and execution context can narrow this contract. [Understand access](/mcp/permissions).

## Input

### Agents / Autónomo / Company schema

```json theme={null}
{
  "additionalProperties": false,
  "properties": {
    "query": {
      "description": "Tool name, namespace, or task, such as automations_create or automations schedule.",
      "minLength": 1,
      "type": "string"
    }
  },
  "required": [
    "query"
  ],
  "type": "object"
}
```

## Output

An object with `tools` and `has_more`. Each matching tool includes its exact name, description and input schema. Eligible OAuth connections may also receive `connected_apps` or `connected_apps_error`.

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](/mcp/results).

## 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.

```bash theme={null}
curl --fail-with-body https://melso.ai/api/mcp \
  -H "Authorization: Bearer $MELSO_MCP_TOKEN" \
  -H "Content-Type: application/json" \
  -H "Accept: application/json, text/event-stream" \
  --data-binary @- <<'JSON'

  "params": {
    "name": "tools_search",
    "arguments": {
      "query": "knowledge history"
    }
  }
}
