MCP server for Nodalync knowledge protocol that enables AI assistants to query content from the Nodalync network with automatic payment channel management and Hedera settlement integration
Nodalync MCP server has 16 tools with complete input schemas and descriptions, but quality is inconsistent. Tool names follow verb_noun convention (query_knowledge, list_sources, publish_content). Descriptions are present (avg ~120 chars) but lack LLM-optimized guidance on WHEN to use each tool vs alternatives. Parameters have types and descriptions, but many lack constraints (enums, ranges, format specs). Output schemas are not documented, critical for agents planning downstream calls. Error handling is minimal; no recovery guidance or actionable error messages visible in code. Security concerns: query_knowledge and deposit_hbar accept financial parameters without visible validation or dry-run support. No tool annotations (readOnlyHint, destructiveHint) despite clear risk levels assigned.
Closes all open payment channels
Closes a payment channel
Deletes content from the local store
Deposits HBAR into the settlement contract
Gets earnings from content queries
Lists available content sources, optionally filtered by topic
Lists all versions of a content item
No output schemas documented. Agents cannot plan downstream calls or extract required fields (e.g., does query_knowledge return transaction_id for chaining to other tools?). Critical for multi-step workflows.
Financial parameters (budget_hbar, initial_balance_hbar, amount_hbar, price_hbar) lack validation constraints, ranges, or dry-run support. Agents could pass invalid amounts or accidentally trigger large transactions without confirmation.
No tool annotations (readOnlyHint, destructiveHint, idempotentHint) despite clear risk levels. Agents cannot distinguish safe reads from destructive writes without parsing descriptions.

Opens a payment channel with a peer
Gets a preview of content without full retrieval
Publishes content to the Nodalync network
Queries content from the Nodalync network. Payment is handled automatically: Opens payment channels when needed, Auto-deposits if settlement balance is insufficient, Returns transaction confirmations in the response
Searches the network for content matching a query
Sets the visibility level of content
Unified status tool that combines health, budget, channel, and Hedera status in one response
Synthesizes new content from existing sources
Updates content metadata
Descriptions lack WHEN-to-use guidance. E.g., query_knowledge vs search_network both search content but distinction is unclear. Agents waste reasoning cycles deciding between similar tools.
No error handling guidance visible. If query_knowledge fails due to insufficient balance, agents have no recovery path. No actionable error messages or retry logic documented.
