## Quality 79/100 (good)

### protocol: 75 (weight 25)

- warn `protocol.modern`: newest supported version is 2025-11-25; 2026-07-28 not supported, older versions are deprecated until 2027-07-28
- n/a `protocol.stateless`: only applies to 2026-07-28 servers
- pass `protocol.transport`: streamable HTTP
- n/a `protocol.list_ttl`: only applies to 2026-07-28 servers

### authorization: n/a (weight 15)

- n/a `auth.prm`, `auth.as_metadata`, `auth.cimd`: no remote uses OAuth
- n/a `auth.secret_in_url`: no templated URL

### tool hygiene: 71 (weight 30)

- pass `tools.descriptions`: every tool has a description
- pass `tools.description_length`: descriptions are concise
- pass `tools.schemas`: every tool has an object input schema
- fail `tools.annotations`: no tool declares readOnlyHint or destructiveHint, so clients cannot tell safe calls from risky ones
- fail `tools.directory_hints`: no tool declares all four of readOnlyHint, destructiveHint, idempotentHint and openWorldHint; missing: SimulatePriceMove (readOnlyHint, destructiveHint, idempotentHint, openWorldHint); SimulateStableswapMove (readOnlyHint, destructiveHint, idempotentHint, openWorldHint); CalculateSlippage (readOnlyHint, destructiveHint, idempotentHint, openWorldHint); …
- pass `tools.token_cost`: about 5,760 tokens to load every tool
- pass `tools.api_dump`: tools are not a one-to-one API dump

### stability: 100 (weight 15)

- pass `stability.changes`: no tool changes in 30 days
- pass `stability.rug_pull`: no tool changed its meaning under the same name

### dependencies: n/a (weight 15)

- n/a `deps.known_vulns`, `deps.mcp_sdk_version`, `deps.resolvable`: no npm or PyPI package

- tools: 11, about 5,760 tokens to load them all
- tool set hash: 4d1224502929a1c0b5b45b6b2daefa6a
- badge: [![protogrid quality](https://protogrid.dev/badge/io.github.icmoore/echoledger-mcp.svg)](https://protogrid.dev/servers/io.github.icmoore/echoledger-mcp)
- Checks run on what our credential-free, read-only probes observe; tools are never called and no code audit is performed.

## Tools (11)

- `AnalyzeBalancerLP`: Analyze a 2-asset Balancer weighted-pool LP position's PnL. Decomposes impermanent loss using the weighted-pool formula where the base token's weight affects IL magnitude. Values are denominated in opp-token units per BalancerImpLoss's convention; fee income is not attributed in v1 because Balancer pools only expose vault-level fees with no per-LP attribution.
- `AnalyzePosition`: Analyze why a Uniswap V2 or V3 LP position is gaining or losing money. Decomposes PnL into impermanent loss, accumulated fees, and net result, with optional real APR if a holding period is supplied. Returns current value, hold value, IL percentage, fee income, net PnL, real APR, and a diagnosis label.
- `AnalyzeStableswapLP`: Analyze a 2-asset Curve-style Stableswap LP position's PnL using the amplified-invariant IL formula where small depegs can produce surprisingly large IL at high A. Values are in peg-numeraire (tokens valued 1:1); fee income is not attributed in v1 (pool-global only); positions whose implied alpha is in the unreachable regime return None on il_percentage, net_pnl, and real_apr.
- `AssessDepegRisk`: Quantify a 2-asset Curve-style Stableswap LP position's exposure to a stablecoin depeg. Computes IL at multiple depeg levels (default 2%, 5%, 10%, 20%, 50%) via the closed-form stableswap-invariant expansion, with an optional V2 constant-product benchmark at each level. Some depeg levels are physically unreachable at high A — unreachable scenarios return null on il_pct, lp_value_at_depeg, and hold_value_at_depeg; the V2 benchmark stays populated.
- `BuildStateTwin`: Read a pool's on-chain state once and return it as a serialized State Twin (JSON): the protocol-specific snapshot plus a content_hash, in the wire form a client rehydrates locally. Use this to pull a single managed-RPC twin, then run any number of counterfactuals (price moves, IL, slippage) client-side, off this server. Covers Uniswap V2/V3, Balancer 2-asset weighted, and Curve 2-asset plain stableswap pools. The endpoint stores and logs nothing — your rpc_url is never persisted.
- `CalculateSlippage`: Calculate slippage and price-impact decomposition for a proposed swap on a Uniswap V2 or V3 pool. Returns spot vs execution price, slippage percentage, slippage cost in output-token units, and price impact. Also returns the maximum trade size that stays within 1% slippage for V2 pools; V3 returns null for that field because tick-crossing math has not yet been inverted.
- `CheckPoolHealth`: Snapshot pool-level health metrics for a Uniswap V2 or V3 pool: TVL in token0 numeraire, reserves, accumulated fees, LP concentration, and swap activity. Answers 'is this a pool I would deposit into?' at the pool level (not position level). num_swaps and fee_accrual_rate_recent are V2-only; V3 returns null for these because V3 has no per-swap history array. A single-block live snapshot also returns null for the LP-concentration and swap metrics (unrecoverable from state alone).
- `DetectRugSignals`: Detect rug-pull signals on a Uniswap V2 or V3 pool via three threshold checks: suspiciously low TVL, top-LP concentration above a limit, and inactive-pool-with-liquidity. Composes over CheckPoolHealth and returns per-signal booleans plus a count-based risk level (low/medium/high/critical). The inactive-with-liquidity signal is V2-only; V3 pools report False for it with a note in details.
- `SimulateBalancerMove`: Project a 2-asset Balancer weighted-pool LP position's value at a hypothetical price change from the CURRENT pool state. The shock is applied to the base-token price in opp units; IL depends on both the shock magnitude and the pool's weights. Returns new value in opp-numeraire, IL at the simulated price, and percentage change.
- `SimulatePriceMove`: Project a Uniswap V2 or V3 LP position's value at a hypothetical price change from the CURRENT pool state (not from entry). A price_change_pct of -0.30 asks 'what if price drops 30% from here'. Returns new value, IL at the simulated price, and percentage change in position value. Fee projection is not modeled (always null).
- `SimulateStableswapMove`: Project a 2-asset Curve-style Stableswap LP position's value at a hypothetical depeg from the CURRENT pool state. The shock multiplies the pool's current alpha by (1 + price_change_pct); at high A, large shocks may be physically unreachable and in that case new_value, il_at_new_price, and value_change_pct are returned as null. Values are in peg-numeraire.
