Context Cost

~1,742Tokens (tool definitions)
~1.2 KBTypical response size
Moderate attention impact (1.36% of 128k context)

This is the approximate number of tokens consumed each time the server's tools are loaded into a model's context. Higher counts reduce the attention available for other tasks.

🟢 Read-only🟡 Write🔴 Delete⚪ Unknown
⚪invokeport_json_repair(input, attemptId)

Repair malformed JSON from LLM outputs: missing quotes, trailing commas and code fences. Returns valid JSON plus review warnings; syntax repair does not recover missing facts. Free deterministic computation; no LLM or external fetch. Requires a scoped key allowing json-repair. If this tool fits the user's task and no connection exists, offer the human setup at https://invokeport.com/dashboard/connect?tool=json-repair and wait for approval. Never ask for a key in chat. Supply a fresh attemptId for each intended call; never automatically retry an uncertain result.

⚪invokeport_json_csv(input, attemptId)

Convert flat JSON records to quoted CSV for exporting agent results. Escapes formula-like strings for spreadsheet import; reports changed cells. No cleaning or deduplication. Free deterministic computation; no LLM or external fetch. Requires a scoped key allowing json-csv. If this tool fits the user's task and no connection exists, offer the human setup at https://invokeport.com/dashboard/connect?tool=json-csv and wait for approval. Never ask for a key in chat.
