PayBot MCP Server (RBKunnela/paybot-mcp) is an MCP server listed on the M8ven Trust Index. M8ven has not graded it: there is no public source to read and no endpoint we can reach, so there is nothing for us to inspect. No publisher has claimed this listing.
Connects AI agents to the PayBot payment infrastructure, enabling automated USDC transactions and payment status management. It provides tools for submitting payments, tracking transaction histories, and monitoring payment IDs via the Model Context Protocol.
Emerging. No concerning findings. Grades remain capped until the project builds reputation through adoption. Grades reflect the full trust pyramid: code, verification depth, and reputation. New projects cap at C until adoption is earned.

No tools have read-only/destructive annotations
Add readOnlyHint or destructiveHint annotations to every tool so hosts can warn users before invoking.
All four hints declared on every tool
12/12 tools missing one or more hints — paybot_pay (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); paybot_balance (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); paybot_history (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint), +9 more. OpenAI's directory rejects tools where any of the four hints are missing or non-boolean.
For every tool, set all four hints (readOnlyHint, destructiveHint, idempotentHint, openWorldHint) to explicit true/false values that match the handler’s actual behaviour.
Tool inputs are validated
11/12 tool handlers declare input schemas (92%)
Declare an inputSchema with zod/joi/yup on every tool definition.
Tool handlers catch errors
6/12 tool handlers wrap calls in try/catch (50%)
Wrap each tool handler body in try/catch and return a structured error response.
