PFT Chatbot MCP
Enables building encrypted, on-chain chatbots on the PFTL network. Allows LLMs to send and receive encrypted messages, register bots, and manage wallet operations.

The grade above is for the source repository. Registries can serve a different version, so we mark the ones we were not able to read.
Disclosed vulnerabilities in this server's declared npm dependencies (via OSV). Whether each is reachable depends on the installed versions.

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
15/15 tools missing one or more hints — create_wallet (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); scan_messages (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); get_message (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint), +12 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
11/15 tool handlers declare input schemas (73%)
Declare an inputSchema with zod/joi/yup on every tool definition.
Tool test coverage
Only 4/15 tools referenced in tests (27%)
Write tests that reference each tool by name so every tool has at least one test.
Production dependencies are patched
1 critical, 7 high severity in production deps — protobufjs@7.5.4 (critical), @grpc/grpc-js@1.14.3 (high)
Run npm audit fix, or upgrade the affected packages to a non-vulnerable version.
Dev dependencies
1 critical/high in dev-only deps (does not ship to users)
Upgrade dev dependencies when convenient.
