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.

Known tools 6

Server instructions

Use Upsilon to measure AI operator token-processing patterns from privacy-preserving telemetry. Use get_sigrank_standard_record for a portable sigrank/0.1-draft compatibility record containing only I/O/W/R and Yield, Leverage, Velocity, SNR (output_fraction), and 10xDEV (log_leverage). Use SigRank tools for the public leaderboard and proof surface: get_leaderboard, get_operator, benchmark_me, rank_if, operator_gap, field_anomaly, who_operates_like_me, compare_to_field, and operator_signature. Analytical tools: rank_paste, simulate_change, diagnose_cascade, suggest_improvements, self_improve, and rank_windows. Construction, Scale V, RS05, Build Archetypes, rank, and percentile are outside base wire compatibility. Contribution Exchange tools are available at https://signalaf.com/api/exchange/mcp. Upsilon describes observable token-processing patterns; do not treat its metrics as cognition, model quality, work quality, employee productivity, or business value.

Known tools 16

rank_paste

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

Inferred read-only
get_sigrank_standard_record

Build a SigRank Standard v0.1-draft portable operator record from available token telemetry.

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?' — benchmarks your token cascade against the live field.

Inferred read-only
rank_if

Answers 'What would it take to reach a target rank?' — takes your current 4 token pillars and a target percentile (e.g.

Inferred read-only
operator_gap

Answers 'What specifically separates operator A from operator B?' — not just 'A has more Yield', but the primary cause, secondary cause, and offsetting weakness.

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.
