AI agents call claim_dividend to retrieve information from Fomox402 without modifying any data. This is common in research, monitoring, and reporting workflows where the agent needs context before taking action. Because read operations don't change state, they are generally safe to allow without restrictions -- but you may still want rate limits to control API costs.
Even though claim_dividend only reads data, uncontrolled read access can leak sensitive information or rack up API costs. An agent caught in a retry loop could make thousands of calls per minute. A rate limit gives you a safety net without blocking legitimate use.
Read-only tools are safe to allow by default. No rate limit needed unless you want to control costs.

Withdraw your accrued $fomox402 key dividends from a specific round. WHAT IT DOES: invokes the Anchor program's distribute instruction to pay out the dividend share owed to your keys on this round. Each key earns (divPerKeyScaled - your_lastClaimed_divPerKeyScaled) / 1e18 × your_keys $fomox402 — i.e., your share of every bid placed AFTER you got each key. WHEN TO USE: any time post-bid. Dividends accrue continuously as later bids come in; you can claim mid-round or wait until settle. Most agents claim once per round, after settle, to minimize fees. WHO CAN CALL: any agent who holds at least 1 key on the round. Reads your key count from the on-chain account, so api_key MUST match the wallet that placed the bids. RETURNS: { tx (Solana sig), gameId, claimedRaw (string, raw atomic units), newDivPerKeyScaledClaimed (the new high-water mark) }. FAILURE MODES: dividend_failed (no_keys) — you don't hold keys on this round dividend_failed (zero_owed) — already up-to-date, no new dividends dividend_failed (rpc) — Solana RPC, retry DIFFERENCES FROM claim_winnings: - winnings = the round-end pot (one-time, only to head bidder) - dividends = per-key passive income (every keyholder, continuous) RELATED: claim_winnings (round-end pot), get_game.yourClaimableDividend (check before claiming), burn_key (advanced — boost your dividend share).. It is categorised as a Read tool in the Fomox402 MCP Server, which means it retrieves data without modifying state.
Register the Fomox402 MCP server in PolicyLayer and add a rule for claim_dividend: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches Fomox402. Nothing to install.
claim_dividend is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the claim_dividend rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.
Set action: deny in the PolicyLayer policy for claim_dividend. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.
claim_dividend is provided by the Fomox402 MCP server (https://bot.staccpad.fun/mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
