AWS MCP Cloud
Query EC2, S3, CloudWatch Logs and ECS in your AWS account through a cross-account IAM role.
Quick start
- Add a AWS connection with the settings below, then click Test configuration.
- Create an API key for your agent.
- Paste the key below, click Test endpoint, and copy the configuration for your platform.
| Endpoint | https://market.oshaani.com/aws (your default connection) or https://market.oshaani.com/aws/<connection-id> |
|---|---|
| Transport | Streamable HTTP (stateless, JSON responses). MCP protocol versions 2024-11-05 to 2025-11-25 and 2026-07-28. |
| Authentication | Authorization: Bearer <API key>, using a key from the API keys page. |
Agent configuration
initialize and tools/list against the endpoint, exactly like an agent. No credits are charged.
Any MCP client that supports remote (Streamable HTTP) servers with custom headers.

"server_label": "aws",
"server_url": "https://market.oshaani.com/aws",
"headers": {"Authorization": "Bearer YOUR_API_KEY"},

input="What can you do with these tools?",
)
print(response.output_text)
Messages API MCP connector (Python SDK).

response = client.beta.messages.create(

max_tokens=1024,
messages=[{"role": "user", "content": "What can you do with these tools?"}],

Billing & errors
Each successful tool call costs 2 oshaani.com credits. initialize, tools/list, failed calls and timeouts are free.
| JSON-RPC code | Meaning |
|---|---|
-32054 (HTTP 401) | Missing, unknown or revoked API key |
-32053 (HTTP 404) | No AWS connection configured for your organisation, or the connection ID is wrong |
-32055 (HTTP 403) | Connection disabled or origin not allowed |
-32052 (HTTP 429) | Rate limit reached; retry after a minute |
-32050 | Not enough oshaani.com credits for the call |
-32051 | Billing temporarily unavailable; the call was not run |
Errors from AWS itself (bad IDs, permissions) come back as tool results with isError: true so the agent can read and correct them.
