> ## 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.

# company_update

> Input, output and examples for the company_update 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>

Update the company's name, public website or instructions. Requires workspace owner or admin.

**Availability:** Agents invitation / OAuth-only.

**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](/mcp/permissions).

## Input

### Agents schema

```json theme={null}
{
  "additionalProperties": false,
  "properties": {
    "instructions": {
      "description": "Guidance every Run in the company receives. Replaces the current instructions; empty clears them.",
      "type": "string"
    },
    "name": {
      "description": "The company's name, as the member says it.",
      "type": "string"
    },
    "website_url": {
      "description": "The company's public website, for example acme.com.",
      "type": "string"
    }
  },
  "type": "object"
}
```

## Output

The updated company profile. Company instructions affect subsequent work.

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.

First discover `company_update` with `tools_search` and confirm that the live schema permits these arguments.

```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'
