Server instructions

Contribution Exchange MCP — discover and act on Contribution Exchange opportunities. Read-only tools: exchange_discover_domain (check if a domain has an Exchange profile), exchange_get_policy (fetch domain policy), exchange_preflight (advisory policy evaluation — no state change), exchange_list_signals (domain-published work signals), exchange_get_signal, exchange_get_attempt. Mutation tools (require auth): exchange_propose (unsolicited proposal — creates a non-binding proposal, NOT a Commitment), exchange_create_attempt, exchange_submit_attempt, exchange_create_proposal_from_attempt. IMPORTANT: No Exchange tool creates a Commitment, authorization, or payment obligation. Signals and proposals are invitational, not binding. Bilateral terms-hash acceptance is required for Commitment formation.

rank_paste

Calculate SigRank cascade metrics from four non-negative token counts without submitting data.

Inferred read-only

get_leaderboard

Read the current public SigRank operator leaderboard.

Inferred read-only

get_operator

Read one public operator profile by codename.

Inferred read-only

simulate_change

Prescriptive 'what if' tool — takes your current 4 token pillars and proposed changes, runs the cascade on both, returns the exact Υ Yield delta, class change, and per-metric diffs.

Inferred read-only

diagnose_cascade

Analyzes your token cascade and diagnoses where you're leaking efficiency.

Inferred read-only

suggest_improvements

Generates ranked, simulated improvement suggestions for your token cascade.

Inferred read-only

self_improve

Runs the full self-improvement cycle in one call: (1) computes your current cascade from 4 token pillars, (2) diagnoses efficiency leaks, (3) generates ranked improvement suggestions, (4) simulates the top suggestion, and (5) returns the complete cycle: diagnosis + suggestions + simulated impact of the best change.

Inferred read-only

rank_windows

Score up to 4 time windows (7d, 30d, 90d, all-time) in one call.

Inferred read-only

benchmark_me

Answers 'How good am I?

Inferred read-only

rank_if

Answers 'What would it take to reach a target rank?

Inferred read-only

operator_gap

Answers 'What specifically separates operator A from operator B?

Inferred read-only

field_anomaly

Finds unusual operators, metric relationships, and outliers in the live leaderboard — without user prompting.

Inferred read-only

who_operates_like_me

Finds operators whose operating signature most resembles yours.

Inferred read-only

compare_to_field

Creates a 'YOU vs FIELD vs TOP 10% vs TOP 1%' comparison table for your cascade metrics.

Inferred read-only

operator_signature

Computes a normalized operating signature from 4 token pillars or a codename.

Indexed

Evidence is source-attributed and does not guarantee that a third-party server is safe. Risk labels are conservative metadata heuristics.
